Introduction

Once you have created a frame of parts in your Tekla Structures model, you will need to connect those parts to complete the model. Tekla Structures contains a wide range of components that you can use to automate the process of creating a model. This chapter explains the basics about components - what they are and how to create them using Tekla Structures. We will begin with the basic concepts, followed by a general description of components properties. Finally, we will show you how to use components in practice.

1.1 Basics of components Introduction

Benefits

Components are tools that you can use to automatically create the parts, welds, and bolts required to connect parts. They are linked to main parts, so, when you modify a main part, the associated component also changes. The main benefits of working with components are: 1. You can save the properties of a component using an easily-identifiable name and keep it for future use. For example, you could save the properties of a W12x65 column base plate connection as W12x65.j*, and use it for several projects. 2. When you modify the size of a profile, Tekla Structures automatically modifies the relevant components. 3. When you copy or move objects, Tekla Structures automatically includes all the associated components.

Component concepts Components are tools that automate tasks and group objects so

that Tekla Structures treats them as a single unit. Components adapt to changes in the model, which means that Tekla Structures automatically modifies a component if you modify the parts it connects. This is an example of how to apply a connection:

Select the main part. Select the secondary part. To see information about the connection, click the connection symbol. The connection automatically creates the required parts, fittings, bolts, etc.

Component types

Components have the following subtypes:

Component type Connection

Description

Examples

Connects two or more parts, and creates all the required objects such as cuts, fittings, parts, bolts, and welds.

Getting Started

Two-sided clip angle, bolted gusset Corbel connection (14)


Symbol

Component type Detail

Modeling tool

System and custom components

Description

Examples

Adds a detail or a reinforcement to a main part. A detail is only connected to one part. When you create a detail, Tekla Structures prompts you to select a part, followed by a point to place the detail.

Stiffeners, base plates, lifting hooks

Automatically creates and assembles the parts to build a structure, but does not connect the structure to existing parts. Modeling tools can include connections and details.

Stairs, frames, towers

Symbol

Beam reinforcement, pad footing reinforcement

Tekla Structures contains hundreds of system components by default. You can also create your own components, custom components . They have following subtypes: •

•

•

•

connection detail part seam

All components are stored in the Component catalog (14). To open the component catalog, use the keyboard shortcut Ctrl+F .

What is a custom component Creating custom components

Component dialog box The component dialog box is in two sections.

Upper part

Use the upper section of the dialog box to save and load predefined settings. For more information, see Save, Load, Save as buttons. For some components the upper section also contains buttons for accessing the bolt, weld and DSTV dialog boxes. For information on handling the saved properties, see Connection properties files (46).

Lower part

The lower section of the dialog box is divided into tabs. This is where you define the properties of the parts and bolts that the component creates. The most common tabs that appear here are: •

•

•

•

•

Picture illustrates the component. It shows just one example, but you can usually use one component in many situations. Parts is where you define the properties of the parts the component creates. Parameters is where you set parameters to control the component (for example, for stiffeners, end plates, chamfers, etc.). Bolts is where you define the number of bolts and their edge distances. General is where you define the direction of the connection or detail and AutoDefaults rules.

Selection order To create a connection you need to select or pick existing parts or points. The default selection order for a connection is: 1. Main part 2. Secondary part(s) 3. If there is more than one secondary part, click the middle mouse button to finish selecting parts and create the connection. Some connection dialog boxes illustrate the selection order for parts using numbers, as shown below. Select the parts in the order shown in the picture:

Details

The default selection order for a detail is: 1. Main part. 2. A point in the main part to show the location of the detail.

Modeling tools

The default picking order for a modeling tool is: 1. Pick one to three point(s) to show the location of the objects the modeling tool creates.

Up direction The up direction of a connection or a detail indicates how the connection is rotated around the secondary part, relative to the current work plane. If there are no secondary parts, Tekla Structures rotates the connection around the main part. The options are: +x, -x, +y, -y, +z, -z. The Picture tab in the dialog box shows the up direction Tekla Structures will use. Tekla Structures also indicates the up direction in the connection symbol:

Getting Started

11


Manually defining up direction

To manually define the up direction: 1. Double-click the connection symbol to open the connection dialog box. 2. On the General tab, change the x, y, or z direction. Try positive directions first. 3. Click Modify to use the new values.

Automatic and default properties Some connection dialog boxes contain list boxes that show property options as graphics. You can select system defaults, AutoDefaults, or have Tekla Structures automatically set the properties.

System default properties

If you leave fields in connection dialog boxes blank, Tekla Structures uses the system default properties. Manual entries, default, automatic and properties in the joints.def file, all override these system defaults. You cannot change system default properties.

Default and automatic properties Icon

More information

Description To have Tekla Structures use a default property in a connection, select the option marked with this symbol. If you use AutoDefaults for the connection, Tekla Structures uses the property defined in the AutoDefaults rules. If you are not using AutoDefaults, Tekla Structures creates the connection using the system default property.

Using AutoDefaults (48)

If AutoDefaults have been used, the actual picture in the default option does not necessarily match the outcome. To have Tekla Structures automatically determine which option to use for a property, select the option marked with this symbol. For example, when you use this option for the stiffener in End plate (144), the connection automatically adds the stiffener to a beam-to-column connection, but does not add it to a beam-tobeam connection.

Field

Description

Up direction

More information

Rotates the connection around the secondary part or detail around the main part.

Up direction (11)

The fields next to the image define rotation angle around the x- and y-axis of the secondary. The upper one is for y- and the lower one for x.

Position in relation to primary part

Available only for details. Select a checkbox next to the images to indicate the position of the definition point of the detail, relative to the main part. Use the Horizontal offset and Vertical offset fields to define the horizontal and vertical alignment of the detail, relative to the main part.

Locked

Prevents modifications.

Locking objects

Class

A number given to all parts the connection creates. You can use class to define the color of parts in the model.

Color settings for parts

Connection code

Identifies the connection. Tekla Structures can display this connection code in connection marks in drawings.

AutoDefaults Rule Group

Automatically sets connection properties according to the selected rule group. To switch AutoDefaults off, select the rule group None.

AutoConnection Rule Group

Automatically switches the connection to another according to the selected rule group.

Using AutoDefaults (48)

Design and Design type tabs Some component dialog boxes include a Design tab, others include a Design type tab. Use the options on these pages to check if the component will bear the UDL (uniform distributed load). This design check is intended for use with imperial units. The Design tab also contains options to: •

Use AutoDefaults rule groups to automatically modify component properties to take the calculated load. To define which AutoDefaults rule group to use, go to the General tab and select the rule in the AutoDefaults rule group list box. For more information, see Reaction forces and UDL (54).

•

Design tab

Use information in an Excel spreadsheet to check connection design and automatically update component properties to bear the UDL. This is useful when you want to check connection design according to other design codes. See Using Excel in connection design (66) .

To check the design of a component that has a Design tab page: 1. Go to the Design tab and select Yes in the Use UDL listbox. 2. To use information in an Excel spreadsheet in the UDL calculation, select Excel in the External design listbox. 3. Enter the information you want to use in the calculation in the remaining fields.

4. Select a connection in the model and click Modify. To view the results of the check, right-click the component symbol and select Inquire from the pop-up menu.The inquire object window opens, which contains a summary of the design checks and related information. See also Using Excel in connection design (66).

Design type tab

To check the design of a component that has a Design type tab page: 1. Open the component properties dialog box. 2. Go to the Design type tab and select Yes in the Check connection list box. Tekla Structures will check the connection each time it is used or changed in a model. 3. Enter the information you want to use in the calculation in the remaining fields. 4. Select a connection in the model and click Modify. 5. Tekla Structures checks the component. A green component symbol indicates that the connection will bear the UDL, red indicates it will not. 6. To view the results of the check, right-click the component symbol and select Inquire from the pop-up menu. The inquire object window opens, which contains a summary of the design check. The summary of the design check shows the part checked, the name of the check, the applied and allowed force and how much capacity has been used, the results and possible solutions.

1.3 Using components Introduction Topics

This section explains how to use components. It also includes examples. Creating components (20) Example: Adding an end plate (21) Example: Adding a base plate and anchor rods (22) Example: Adding a beam to column connection (23) Viewing components (23) Modifying components (24) Tips on working with components (26)

Creating components You create different types of component in different ways. For example, you select existing parts to indicate which members a connection or a detail is attached to. You need to pick points to indicate the location or length of a detail or a modeling tool. See also Selection order (11). When you create connections, Tekla Structures prompts you to select the main part (the part secondary parts connect to), then the secondary part(s). For an example of using a connection, see Example: Adding an end plate (21).

Status

Tekla Structures uses different-colored component symbols to show the status of connections and details:

When applying a component that you are unfamiliar with, accept the default properties and apply the component. Then look to see what needs to be modified. This is quicker than trying to set the values for the component before seeing what the component actually creates.

Example: Adding an end plate This example shows how to create an end plate connection. The End plate (144) connection connects two beams, or a beam to a column, using a bolted end plate. To create the end plate connection: 1. In the the com compo pone nent nt cat catal alog og,, ente enterr 144 and click Search. 2. Doub Double le--clic clickk the the End plate (144) component.

Using components

Modifying components To modify a component, double-click the component symbol in the model. The component dialog box appears. This is where you modify the component properties.

If you have Select component switched on , you do not have to pick component symbol, but you can just pick any object belonging to a component. This is the only method for selecting custom parts, because they do not have any symbol. You can also indicate which connections and details are affected by the modifications: •

•

Modify connection type: If you have selected several connections and details, clicking the Modify button modifies all the selected connections and details irrespective of their type. If the connection type is not the same as in the dialog box, Tekla Structures changes the connection type. Ignore other types: Tekla Structures only modifies connections and details of the type shown in dialog box.

Conceptual components Depending on the Tekla Structures configuration you are using, you can create either detailed or conceptual components. Conceptual components are meant to be used as reference information for further fabrication detailing. Conceptual components look similar to detailed components but do not include the option to change part numbering or assembly numbering settings. Conceptual components can be created only with Engineering and Cast in Place configurations. However, you can edit conceptual components in Full, Steel Detailing, or Precast Concrete Detailing configurations. Conceptual components can be converted to detailed components that include all the information needed for fabrication, such as assemblies, cast units, and reinfor cing bars. The conversion to detailed components can be done in Full, Steel Detailing, or Precast Concrete Detailing configurations. Modifying part properties, such as the size of the component main part, does not automatically convert a detailed component to a conceptual one, or vice versa. For example, if you use the Engineering configuration and modify the model, detailed components do not convert to conceptual components.

Automating the detailing process If you have a standard way of configuring connections, save time by saving the connection properties once. Store them in firm or project folders for future use. See Firm and project folders. Tekla Structures includes AutoConnection and AutoDefaults tools to automate the modeling process. So you can customize Tekla Structures to suit a particular project and the way you work. See AutoConnection (39)and AutoDefaults (44). There are three levels of automation that you can help you work faster and more accurately.

Tips on working with components No component created

If you have difficulty applying a component, check the status bar for prompts. For example, you may need to click the middle mouse button to stop selecting parts, before Tekla Structures creates the component.

Many parts found

If you are applying a connection that only allows for one secondary part, you may see the message Many parts found on the status bar. This means that Tekla Structures cannot determine which parts to connect. You may have several parts in the same location, or the view may be set too deep.

Switch parts on/ If the component does not create the parts you need by default (for example, stiffener plates), look off for a switch to turn them on. If there is no switch, try entering a value in the thickness field for that part (for example, on the Stiffeners tab). If the component creates parts you do not need, look for the switch to turn them off. If there is no switch, enter a zero (0) in the thickness field for that part.

Default: Tekla Structures creates stiffeners or uses value retrieved from AutoDefaults.

Automatic: Tekla Structures creates or omits stiffeners depending on the situation in the model.

Tekla Structures does not create stiffeners

Entering valid profiles

You need to specify profiles for some components. If a component fails, try entering a valid profile.

1.4 Defining parts and plates Use the Parts tab to define the parts that Tekla Structures creates when you use a component.

Topics

Using the dialog box (27) Dimensioning parts (27) Defining materials (29)

Using the dialog box Some components list all parts on one tab, others list parts on separate tabs as shown in the following examples.

One Parts tab

Several Parts tabs

Where there is one tab, the label is usually Parts or Plates.

Parts can also appear on separate tabs. For example, in connection 56, Corner tube gusset, the parts appear on both the Gusset and Brace conn tabs.

Dimensioning parts Use the Parts tabs to dimension specific part types in components.

Getting Started

27

Defining parts and plates

To delete a part, enter zero (0) in the t (thickness) field.

Plates Enter the following dimensions for plates:

Dimension

Description

t

Plate thickness

b

Plate width

h

Plate height

You do not have to enter these dimensions for every component type, as Tekla Structures determines the plate shape differently for different components. For example, in end plate connections, Tekla Structures calculates width and height using the number of bolts and bolt edge distances. Click Help in a component dialog box to check which dimensions you need to enter.

Beams To specify a library or parametric profile to use for beams: •

Enter the profile name.

•

Or click

, and select a profile from the profile catalog.

The profile must exist in the profile catalog.

Part position number Use the Pos_no field to enter the part position number for each part the component creates. This overrides the settings on the Tools > Options > Options... > Components tab. Specify a prefix and a start number , as shown below.

Prefix Start number Some component dialog boxes have a second row of Pos_no fields for you to enter the assembly position number.

Getting Started

28


Using the Components tab To set the default prefix and start number for all the parts that components create, click Tools > Options > Options... > Components. You define different prefixes and start numbers according to the part’s relationship to other parts in the component. Separate the prefix and part number using the \ character (for example, p\1).

1.7 AutoConnection Introduction

Use AutoConnection to automatically select and apply connections with predefined properties to selected parts in a model. With AutoConnection, Tekla Structures automatically creates similar connections for similar framing conditions. You can use AutoConnection to quickly add connections individually, in phases, or project-wide. This is a useful technique when you are working on a large project using many connections, modifying a model, or importing modified profiles. AutoDefaults allows you to modify standard connection properties and save them for use in specific

circumstances. You can define rule groups and rule sets for both AutoConnection and AutoDefaults to use for different conditions within the model. You can use AutoDefaults together with AutoConnection to define connection properties. You can also use AutoDefaults to define connection properties and apply them to a single connection.

Test model

See also

Before using AutoConnections and AutoDefaults in a working model, we recommend that you create a test model, and create all the connection conditions in it that you need for a particular project. You can then use this test model to check the rules and properties of various connection types. It also acts as a quick reference for connection information. AutoConnection setup (40) AutoConnection rule groups (41) AutoConnection rule sets (42) Rules.zxt (43) Changing a connection (43) Using AutoConnection (43) AutoDefaults (44) AutoConnection and AutoDefaults rules (48)

AutoConnection setup With AutoConnection you can define groups of rules which Tekla Structures automatically applies when you use AutoConnection to create connections in a model. For example, you can create separate rules for different standards, projects, manufacturers, and even individual models. By using a rule group to select connections and connection properties, you can create connections automatically, without having to select each connection and define its properties individually.

Tree structure

To access the AutoConnection Setup dialog box, click Detailing > AutoConnection > AutoConnection Settings.... The connection types used in various cases are shown in a tree structure:

AutoConnection

Icon

Type

Description

Rule group

The 1st level in the tree shows the rule groups. These are user-definable. They help you to group the rules according to different standards, projects, manufacturers, and models.

Framing condition

The 2nd level shows the different predefined framing conditions (connection types). Tekla Structures creates them automatically and you cannot change them. The framing conditions include the following: beam to beam web, beam to beam flange, beam to column web, beam to column flange, beam splice, and column splice.

Rule set

Under each framing condition you can create rule sets to specify which connection to use for specific conditions within the model.

Connection

The connection to apply if the rule set criteria are met.

To apply a particular connection, the conditions within the model have to match all the rules in the branch containing the connection. If you do not want to apply a connection for certain rules sets, right-click the connection name and then select No connection from the pop-up menu.

Getting Started

41

AutoConnection

The order of the rules in the tree is important. Tekla Structures uses the first rule that matches the conditions within the model, so you should place the most limiting rule highest in the tree, and the most generic, lowest.

Restrictions

AutoConnection has the following restrictions: •

•

See also

You can have a maximum of two secondary parts in the connection (for example, you cannot use complex gussets with several secondaries). AutoConnection uses profile height and ID number as the criteria for determining 1. secondary and 2. secondary parts. AutoDefaults only affects connection parts (clip angles, shear tabs, end p lates, …), bolts, and welds. AutoDefaults cannot change beam profiles or the connection number.

For more information on rules, see AutoConnection rule groups (41)and AutoConnection rule sets (42). For more information on how to use AutoConnection, see Using AutoConnection (43).

AutoConnection rule groups Before using AutoConnection, you need to define rule groups, so that you can group the rules according to different standards, projects, manufacturers, etc. To create a new rule group: 1. Open your test model. Click Detailing > AutoConnection > AutoConnection Settings.... 2. Right-click an existing rule group, and select New rule group from the pop-up menu. 3. Double-click the group New and rename it. Give it a distinctive name.

Give the rule group a name that reflects the group of connections that you want to create. For example, use the fabricator's name, the project name, or any name that will clearly identify the connection rules that you want to use for a specific model. When you create a new rule group, Tekla Structures automatically adds the framing conditions branches under it (beam to beam web, beam to beam flange etc.).

AutoConnection rule sets Each framing condition can contain rule sets, which you can use to specify which connection to use for specific conditions within the model. You only need to create AutoConnection rule sets if you plan to use different connections to connect similar framing conditions. For example, you have beam to beam connections, some require clip angles, others need shear tabs. In this case, you need to set up rule sets to determine where each connection type should be used.

Creating a rule set

Creating a subrule set

To add a new rule set under a framing condition: 1. Right-click the framing condition. A pop-up menu appears. 2. Select New rule set. A New entry appears in the tree. 3. Give the new rule set a descriptive name. 1. Right-click an existing rule set. A pop-up menu appears. 2. Select Create additional rule sets. A New entry appears in the tree. 3. Give the new subrule set a descriptive name. Creating a new rule set or subrule set only adds a rule set to the setup tree. You need to define its contents separately. See AutoConnection (39).

Getting Started

42

AutoConnection

Editing a rule set

You can edit the contents of a rule set (for example, change the name or add rules to it): 1. 2. 3. 4. 5.

Right-click the rule set. A pop-up menu appears. Select Edit rule set... to open the AutoConnection Rules dialog box. Select a rule from the Available rules list. Click the right arrow button to move the selected rule into the list of rules in the rule set. In the right pane under Rules in rule set, fill in the acceptable values for the rule. You can either define an exact value, or minimum and maximum values. 6. The name you enter in the Rule set name field is shown in the setup tree.

The order of the rules in the tree is important. Tekla Structures uses the first rule that matches the conditions within the model, so you should place the most limiting rule highest in the tree, and the most generic, lowest. You can change the priority of a rule set by right-clicking the rule set and selecting Move Up or Move Down. For more information on rules, see AutoConnection and AutoDefaults rules (48).

Rules.zxt When you use AutoConnection, Tekla Structures creates an Attributes subfolder in the current model folder and saves the AutoConnection information in a zipped text file called rules.zxt. You can copy this file to the project or firm folders to make it available for other models (see also Project and firm folders ). Each time you modify AutoConnection setup you need to recopy this file to the firm and/or project folders. When you copy this file for use in other projects, remember to restart Tekla Structures to use the new setup.

Changing a connection To change the connection in a rule set, use the Component catalog dialog box which lists all the Tekla Structures connections available in the connection toolbars.

1.8 AutoDefaults Introduction

Use AutoDefaults to automatically apply the correct properties to existing connections. When you use AutoDefaults, Tekla Structures automatically creates connections with predefined properties. For example, you can use AutoDefaults to automatically adjust the thickness of each base plate you create, according to the main part profile. If the main part profile changes, Tekla Structures will also automatically adjust the thickness of the base plate.

AutoDefaults

AutoDefaults setup With AutoDefaults you can create rules defining when to use different predefined connection properties. When you modify connections (for example changing the beam size), Tekla Structures automatically redefines the connection properties using AutoDefaults setup. Use AutoDefaults to modify standard connection properties and save the modified properties for use in specific situations.

Tree structure

To open the AutoDefaults setup dialog box, click Detailing > AutoConnection > AutoDefaults Settings.... The connection types used in various cases are shown in a tree structure:

Icon

Type

Description

Rule group

The 1st level in the tree contains rule groups. The rule groups are user-definable. They help you to group rules according to different standards, projects, manufacturers, and models.

Connection page

The next two levels show all the connections available on the toolbars. They are predefined and you cannot change them.

Connection Rule set

Under each connection you can create rule sets to specify which connection properties to use when specific conditions within the model are met.

Connection properties file

Every branch in the tree ends with connection properties file(s) (for example, standard.j144). You can save connection properties that you want to use again. See Saving connection properties (46).

Getting Started

46

AutoDefaults

Rule sets

You define AutoDefaults rule sets in the same way as AutoConnection rule sets. See AutoConnection rule sets (42). Tekla Structures saves the AutoDefaults rules in the defaults.zxt file in the current model folder. You may want to copy defaults.zxt and all the connection properties files associated with it (for example, sec_0-190.j141) to the firm or project folders to use in other models. See Defaults.zxt (47).

Connection properties files By default, each connection has a standard properties file which defines the standard properties for the connection (for example, standard.j144). You can save connection properties that you want to use again in separate properties files and give them a distinctive name. Saving connection properties To save connection properties for later use in similar conditions within the model, you can save them in a properties file: 1. Set the properties you want to save (for example, bolt, profile, material properties). 2. In the Save as field, enter a distinctive name for the connection properties. Enter the same name in the Connection code field and click Save as.

When you save connection properties to use with AutoDefaults, it is a good idea to enter the same name in the Save as and Connection code fields on the General tab. This means you can easily check later which properties Tekla Structures used in specific situations. Tekla Structures does not automatically show the AutoDefault values in the connection properties fields. Tekla Structures creates the properties file in an Attributes subfolder in the current model folder. The filename consists of the name you entered in Save as and the extension .jXXX, where XXX is the connection number (for example, sec_0-190.j141).

Access to properties files To view the list of properties files for a certain connection: 1. In the AutoDefaults Setup tree, select a properties file (for example, standard.j144). 2. Right-click the selected properties file. A pop-up menu appears. 3. Click Select connection parameters.... Tekla Structures displays the Attribute File List dialog box, containing the existing properties files for the connection.

Defaults.zxt When you use AutoDefaults, Tekla Structures creates an Attributes sub-folder in the current model folder and saves the AutoDefaults setup in a zipped text file, defaults.zxt. You can copy this file to the project or firm folders to make it available in other models. See also Project and firm folders . Each time you modify the AutoDefaults setup, you need to recopy this file to the firm, or project folders. When you copy this file for use in other projects, remember to restart Tekla Structures to use the new setup.

Getting Started

47

AutoDefaults

We do not recommend that you edit the defaults.zxt file using a text editor, but if you do so, check that you use the right syntax. The easiest way to unpack the .zxt file is to change the file extension zxt to txt.gz and unpack the file using WinZip. Change the extension back to zxt when you have finished. You do not need to repack the file after editing it, Tekla Structures can also read the unpacked file.

Priority of rule sets Tekla Structures processes AutoDefaults rule sets in the order in which they appear in the tree, so you can control the selection of properties. Usually, one framing condition, profile type, and orientation can have several property combinations, for example, a d ifferent profile height. Example

For example, if you have properties files and rules for maximum profile heights of 150, 160, 170 and 190 mm, and AutoDefaults is selecting properties for a height of 158 mm, three properties files are valid. AutoDefaults selects the first one to match (in this case, 160 mm). Where there is no match, you will need a default rule and properties file.You should set the default rule so that it does not define the profile height and is the last item in the branch. In this way the default rule will always be the last one to match and any properties file that matches the profile height will override it.

Editing connection properties To edit connection properties in the AutoDefaults Setup tree: 1. Right-click a connection standard.j file (for example, standard.j144). A pop-up menu appears. 2. Select Edit connection parameters to open the connection dialog box. 3. Set the properties as you would when manually creating connections. 4. Type a descriptive name for these properties in the Save as text box and click Save as. Use a name that distinguishes these as AutoDefaults setup. 5. Click Cancel to close the dialog box and return to the AutoDefaults setup dialog box.

If you click OK to close the dialog box, you need to load the default properties next time you use this connection. This ensures that AutoDefaults can modify the properties. 6. Right-click the standard.j again. Click Select connection parameters.... 7. The Attribute File List opens. It contains the properties that have been set and saved in the connection dialog box. 8. You can now apply any of the properties that have been saved in a rule set.

Using AutoDefaults To use AutoDefaults for a single connection: 1. Open the connection dialog box. 2. On the General tab, select a rule group from the AutoDefaults rule group list. The rule group cannot be None. 3. On all the tabs, set the fields that you want AutoDefaults to override to Default by selecting the options marked with the arrow symbol . 4. Click Apply to create the connection using AutoDefaults.

AutoDefaults

To quickly set all the fields in a dialog box to Default, load in the connection dialog box.

How to use AutoDefaults effectively Use default values when you create a connection, then use AutoDefaults to modify the properties. If you manually modify connection properties after using AutoDefaults, Tekla Structures will not automatically update the connection properties, even if AutoDefaults is active. AutoDefaults does not change connection properties that have been modified. It only modifies connection properties in fields containing the default properties. For example, you have manually set a base plate thickness of 20 mm in the Base plate dialog box of a connection. AutoDefaults is active and sets plate thickness according to the main p art profile. If you modify the main part profile, Tekla Structures does not update the base plate thickness. It remains at 20 mm.

Checking AutoDefaults properties To check the properties AutoDefaults has applied to a connection: 1. Double-click the connection symbol to open the connection dialog box. 2. In the list box in the upper left corner of the dialog box, select . 3. Click Load. Tekla Structures shows the applied properties in the fields. You can also see all the combined properties used for that connection.

Checking AutoDefaults rules You can check which rules AutoDefaults has used for a particular connection. 1. Select the connection symbol and right-click. 2. Select Inquire. Tekla Structures shows the rule group and rule sets that the connection passed. You can also see all the properties files used for that connection.

AutoConnection and AutoDefaults rules Introduction You can use the rules listed in the sections below to accurately select connections and connection properties when using AutoConnection and AutoDefaults. Using these rules you can create your own standards to apply project or company defaults. General

Combining and iterating properties AutoDefaults includes these features:

Feature

Using these features

Description

Combining

You can save connection properties files covering different groups of properties, then use these files to define many rules. For example you can have one file for bolt properties and another for profile properties. Tekla Structures combines the files when it runs AutoDefaults.

Iterating

Tekla Structures tests properties until the connection symbol is yellow or green. Iteration changes connection properties automatically if connection fails, even if the rules would match. If Connection Check is set on, the iteration results in connection properties that have passed the check.

To use either of these features for a rule set: 1. Click Detailing > AutoConnection > AutoDefault Settings...

Getting Started

51

AutoDefaults

2. Browse the tree and right-click a rules set. 3. Select Edit rule set... 4. Set Parameters files selection to one of the following options:

Option

Description

Use combination of first parameters

Tekla Structures uses the properties files it finds in the first matching sub-rule set and does not check other rule sets.

Iterate until the connection symbol is green

Tekla Structures checks sub rule sets until it finds matching properties that leave the connection symbol green.

Iterate until the connection symbol is yellow

Tekla Structures checks sub rule sets until it finds matching properties that leave the connection symbol yellow.

Use combination of all parameters

Tekla Structures checks all rule sets and uses properties files in all matching rule sets. The order of properties files is important, since the last overrides.

The order of files in the tree is important. When Tekla Structures combines the properties files, the most recent files (the lowest in the tree) override previous ones. If you leave properties blank, Tekla Structures does not override previous properties with blank properties.

Limitations Tekla Structures cannot iterate properties files directly. Use a single iteration rule set with sub rule sets. You cannot have many parallel iteration rule sets. Use a single iteration rule set and place it just before the default rule set. Place the combination rule sets above the iteration rule set in the tree. Combination rule sets can only be one level deep. Tekla Structures disregards empty rule sets, so include at least one rule in each rule set.

See also

Combining properties (52) Iteration with connection check (52)

Combining properties The AutoDefaults combine feature combines separate properties files into one file. This means you define fewer files, because you use one file for several rules. If files contain different values for the same property, Tekla Structures uses the last property it finds. See the image below.

Iteration with connection check This example shows how you can use the iteration feature of AutoDefaults. In this example iteration sets the number of bolts according to the result of the connection check. When using this rule group for a connection in the model, AutoDefaults sets the number of bolts until the connection symbol is green.

Getting Started

53

AutoDefaults

The iteration rule forces Tekla Structures to tests sub r ules until the connection symbol is green in the model.

Creating iteration rules

First, create connection properties files for each number of bolts. See Editing connection properties (47). 1. Click Detailing > AutoConnection > AutoDefaults Settings... 2. Right-click the tree and select New rule group. Click the rule group and rename it to "Iteration example". 3. Browse the tree and find connection 144. Right-click it and select Create additional rule sets.... 4. Right-click the rule set and select Edit rule set..., to open the AutoDefault rules dialog box. 5. Change the Rule set name to "ITERATION". 6. Set Parameters file selection to Iterate until the connection symbol is green. 7. Click OK. 8. To create a rule set "2 bolts", right-click the first rule set and select Create additional rule sets.... 9. Right-click the new rule set and select Edit rule set.... AutoDefault rules dialog box appears. 10. Select rule Secondary 1 depth and set the minimum and maximum depth values for two bolts. 11. Set Parameters file selection to Use combination of first parameters. 12. Click OK. 13. Right-click the connection properties file standard.j144, and click Select connection parameters.. to open the Attribute File List dialog box. Select the properties file for two bolts and click OK. 14. Repeat steps 8 to 13 for other rule sets.

Using rules and check together

You can use the connection check result when applying AutoDefaults with iteration. If a rule matches, but connection do not pass the check and symbol remains red, AutoDefaults continues testing other rules and properties until the connection symbol is green. To apply a rule group and connection check for a connection: 1. 2. 3. 4.

Open the connection properties dialog box. Load the properties. Click General tab and set AutoDefaults Rule Group to the "Iteration example" you created. Click Design type tab and set Connection check to Yes.

Getting Started

54

AutoDefaults

5. Enter the load from secondary members in the fields Shear, Tension, Moment. 6. Click OK to create the connection.

Checking

To see which rules AutoDefaults used, right-click the connection symbol, and select Inquire. To see which values AutoDefaults set, double-click the connection symbol to open the connection dialog box, select , then click Load.

Reaction forces and UDL You can save reaction forces: •

•

In the user-defined attributes of a part (for AutoConnection and AutoDefaults). On the Design tab in the connection dialog box (for AutoDefaults).

Using reaction forces

When you use reaction forces in a rule and AutoDefaults is activate, Tekla Structures first searches for reaction forces in the corresponding connection’s properties. If they do not contain reaction forces, Tekla Structures searches the user-defined attributes of the secondary part of the connection. If Tekla Structures finds no forces there, you cannot use reaction force rules.

Shear force calculation

Shear force calculation is the exception. If you have not given any reaction force values, shear force is calculated using the UDL shear force routine. The UDL calculation is mainly intended for use with imperial units. It uses the yield stress value, profile dimensions, and UDL percentage to calculate the maximum allowable shear force. Tekla Structures compares the result with the Shear force rule in AutoDefaults. •

•

•

UDL for AutoConnection

UDL for AutoDefaults

Yield stress is defined in the material catalog. Profile dimensions come from the profile catalog. UDL percentage is taken either from the connection dialog box or from an advanced option.

To switch on UDL calculation for AutoConnection: 1. On the Design tab in the connection dialog box, set the field Use UDL to Yes. 2. Enter the UDL percentage in the UDL % field. If this field is blank, Tekla Structures uses a default percentage (set using the advanced option XS_AUTODEFAULT_UDL_PERCENT). To switch on UDL calculation for AutoDefaults: •

•

Set the advanced option XS_AUTOCONNECTION_USE_UDL to TRUE. Use the advanced option XS_AUTODEFAULT_UDL_PERCENT to set the UDL percentage.

1.9 Using the joints.def file This section explains how to use the joints.def text file to set the default properties for different connection types. Not all connections use joints.def.

About joints.def Changing the joints.def file changes the default values for different connection types. You can open the joints.def file in any standard text editor.

Tekla Structures only uses the values in joints.def for blank fields. AutoDefaults and manual entries override joints.def.

If you use joints.def, you can still use some system default properties. To force Tekla Structures to use the system default for a particular property, give it the value -2147483648 in joints.def. By default, Tekla Structures includes the Tekla Structures searches for

joints.def

in the standard search order.

How joints.def works For each connection type, Tekla Structures follows these steps to assign bolt and part properties. 1. Tekla Structures determines bolt diameter and number of bolts according to the following criteria:

Connection type

According to

Clip angle

Secondary beam height

Shear plate


End plate


Gusset

Length of angle profile

Diagonal

Profile height

2. Tekla Structures uses bolt diameter to assign other bolt and part properties.

How to read joints.def Lines beginning with // are comment lines. They are there to help you read the file, Tekla Structures does not use the information in comment lines. The first few lines contain some general settings: Set the following line to the unit of measure appropriate to the version you are using (for example, inches in the Imperial version).

To have Tekla Structures use the default values in joints.def, set the following line to 1. Set it to 0 to have Tekla Structures use the system defaults.

Profile type-dependent bolt dimensions For some connections, such as Clip angle (141) and Two sided clip angle (143), Tekla Structures calculates the bolt size according to the profile size. In this type of connections, Tekla Structures takes the bolt size from the PROFILE TYPE-DEPENDENT BOLT DIMENSIONS section of joints.def file if you leave the corresponding fields blank on the Bolts tab:

The options are:

Option

Example

Description

width

Width of the profile

one bolt firsthole

For single bolts, distance from the heel of the profile angle to the first hole.

two bolts firsthole

For two bolts, distance from the heel of the profile angle to the first hole.

pitch

Distance between bolts from the center of each bolt. For vertical and horizontal bolts.

To find the bolt dimensions to be used with an L6X6X1/2 profile in a clip angle connection: 1. Tekla Structures searches the rows beginning PROFILEBOLTDIM for L6X6X1/2 in the PROFILE TYPE-DEPENDENT BOLT DIMENSIONS section of joints.def. 2. If there is no match, Tekla Structures searches the rows beginning ANGLECLBOLTPART in the CLIP ANGLE section of joints.def.

How Tekla Structures uses joints.def This example explains how Tekla Structures calculates bolt diameter and other properties using joints.def. We are using a Bolted gusset (11) connection. The height of the diagonal profile is 10". •

•

Tekla Structures calculates bolt size and number of bolts according to profile height. It searches the BOLTHEIGHT rows for a profile height of 10". The profile height is greater than 8.0 but less than 12.0, so Tekla Structures uses the row with the profile height 8.0. This sets the bolt diameter to 0.75.

1.10 Using Excel in connection design You can link system components and Excel spreadsheets, so when a component is applied or modified, an associated Excel spreadsheet application can be run. The configuration information is passed from the component to the spreadsheet, calculation run within the spreadsheet and component properties passed back to the connection.

You can use Excel in connection design for all steel components that have the Design tab in their properties dialog box.

Tekla Structures includes sample spreadsheet for connection design and a template spreadsheet you should use to create your own spreadsheet applications to use with Tekla Structures components. Before you start: •

•

Create the connections and parts. Create the Excel spreadsheet for connection type, or use a predefined file. See more in Setting up Excel files (67).

To use the Excel spreadsheet for connection design: 1. 2. 3. 4.

Double-click the connection to open the connection properties dialog box. Go to the Design (or Design type) tab and select Excel in the External design list box. Click Modify. The connection properties are transferred from Tekla Structures to a connection type specific Excel spreadsheet, where the properties are calculated. 5. The calculated properties are saved to an output file. 6. The modified properties are transferred back to Tekla Structures and the connection is modified according to the changes.

Topics

Setting up Excel files (67) Sample implementation (67) Indicating component status (70)

Setting up Excel files The following list describes what kind of files are needed for performing connection design with Excel: •

•

Visual Basic script file linking Tekla Structures with external software. Excel spreadsheet containing calculations. Component type specific spreadsheet, which contains predefined calculations. When you run the connection design, the connection properties and information of the main and secondary parts are transferred to the Input and Component sheets of the spreadsheet. •

•

•

Connection specific result file , which displays the modified connection properties is stored to model folder. •

•

•

File names and locations

This file is created automatically from the Calculation sheet of the spreadsheet. The file is updated each time you modify the connection. Calculation results can be stored as Excel spreadsheet, HTML or PDF format, depending on how calculation spreadsheet is configured.

Excel.vb

file (located in the ..\Tekla

folder) defines the Excel spreadsheet file names and the locations. Excel searches for the spreadsheet in the following order and with following name: Structures\\environments\common\exceldesign

1. File named component_

+ number or name + .xls,

from the current model folder:

..\\exceldesign

For example,

..\test_model\exceldesign\component_144.xls

2. File name and path defined with advanced option XS_EXTERNAL_EXCEL_DESIGN_PATH: XS_EXTERNAL_EXCEL_DESIGN_PATH (=%XS_DIR%\environments\common\exceldesign\) + "component_" + number + ".xls"

By default, the result file is stored in the model folder and named with component ID. For example, component_9502_res.xls.

Reinforcement

Introduction

Once you have created a model of concrete parts, you will need to reinforce the parts. This chapter explains how to create reinforcement in Tekla Structures. It also includes a general description of reinforcement properties and an overview of reinforcement commands.

Audience Assumed background

This chapter is aimed at concrete detailers and designers. Before you start to create reinforcement, you need to have concrete parts in your model, as explained in Concrete Detailing. Running the structural analysis as explained in Analysis and Design gives you the required area of reinforcement. Read Loads for instructions on how to create loads.

Numbering reinforcements

2.1 Getting started with reinforcement In Tekla Structures, you can use different methods to create re inforcement. You can create: •

•

•

•

Concepts

Single reinforcing bars Reinforcing bar groups Reinforcement meshes Reinforcement components.

We recommend that you use reinforcement components to create reinforcement whenever possible. They are adaptive, attached to a concrete part, and updated automatically if the dimensions of the reinforced part change, for example. Then create additional reinforcing bars using other tools. Reinforcing bar groups consist of several identical, or very similar, bars. Tekla Structures always

treats these bars as a group, modifies them in the same way, deletes them all at the same time, etc. Reinforcement meshes include bars in two perpendicular directions,

i.e. main bars and crossing bars. Tekla Structures treats mesh bars as one unit but distinguishes the main and crossing bars.

Reinforcement properties

Filtering by properties

Every reinforcement object has properties which define it (for example, grade, diameter or size, minimum bending radius). Use the reinforcement properties dialog boxes to view or modify the properties of reinforcement. Click Detailing > Properties > Reinforcement to open reinforcement properties dialog boxes, or double-click an existing reinforcement object in the model. You can use reinforcement properties in filters. For example, you can select, modify, or hide reinforcing bars based on their properties.For more information, see Filtering objects.

In reports and drawings See also

You can include reinforcement properties and user-defined attributes in drawing and report templates. Basic reinforcement properties (74) Getting Started (7) with Detailing

2.2 Basic reinforcement properties This section explains properties that are common to most types of reinforcement in Tekla Structures.

Name

You can enter names for reinforcing bars. Tekla Structures uses names in reports and drawing tables.

Grade

The strength of the steel used in reinforcing bars. Can also indicate other factors, such as the weldability or surface deformations of the bar.

Size

Depending on the environment, the nominal diameter of the bar, or a mark that defines the diameter.

Bending radius

Complies with the design code you are using. Main bars, stirrups, ties, and hooks usually have their own minimum internal bending radii, which are proportional to the diameter of the reinforcing bar. The actual bending radius is normally chosen to suit the size of the mandrels on the bar-bending machine.

Bending types

Tekla Structures reinforcing bar bending types are recognized using internal bending type definitions. Internal bending types are hard coded to the software. However, these internal bending types are mapped to area specific reinforcing bar bending type codes in the rebar_schedule_config.inp file in the ..\Tekla Structures\\environments\\system\ folder. This file can be localized to match local requirements. For more information on internal bending types, see Reinforcing bar bending types (116).

Reinforcement catalog

Grade–size–radius combinations are predefined in the reinforcement catalog. You can select which catalog to use, and add, modify, and delete the information it contains. See The Reinforcing Bar Catalog.

Select...

To define the grade, size, and bending radius of a reinforcing bar, click Select... next to the Grade, Size, and Bending radius fields in the Reinforcing bar properties dialog box. The Select reinforcing bar dialog box appears, showing the available bar sizes for the chosen grade. You can also define whether the bar is a main bar or a stirrup or tie.

Reinforcement

74

Basic reinforcement properties

You can also enter the grade, size, and bending radius of individual reinforcing bars using the appropriate fields in the Reinforcing bar properties dialog box.

Class

Bar groups

Use Class to group reinforcement. To display reinforcing bars of different classes in different colors, click View > Representation > Object Representation... and select Color by class from the Color list box. For more information, see Color settings for parts. Reinforcing bar groups mainly have the same properties as single reinforcing bars. They can also have the following extra properties: •

Hooks (75) Concrete cover (76) Spacing reinforcing bars (78) Omitting reinforcing bars (78) User-defined attributes of reinforcement (79) Meshes (79)


Hooks To add hooks to the ends of reinforcing bars for anchoring purposes, use the Hooks section of the Reinforcing Bar Properties dialog box, or the Hooks tab in the Reinforcement Mesh Properties dialog box:

Reinforcement

75


The options for the hook at the beginning and end of the bar are:

Option

Description No hook Standard 90-degree hook Standard 135-degree hook Standard 180-degree hook Custom hook

The reinforcement catalog contains predefined dimensions for all standard hooks (minimum bending radius, minimum hook length). See The Reinforcing Bar Catalog .

Custom hook

To manually define the angle, radius, and length of a hook, select the Custom hook option and enter values to the following fields in the Reinforcing Bar Properties dialog box:

Field

Description

Angle

Enter a value between –180 and +180 degrees.

Radius

Internal bending radius of the hook. Use the same radius for the hook and for the reinforcing bar. If the hook and the reinforcing bar have different radiuses, Tekla Structures does not recognize the shape of the reinforcing bar.

Length

Angle

Length of the straight part of the hook. If the length is set to zero, no hooks are created.

Radius Length

Concrete cover Reinforcing bars need a concrete cover, to protect them against harmful elements, such as the weather and fire. When you create single bars, Tekla Structures uses the thickness of concrete cover to determine the position of the bar. You pick points to define the shape and plane of the bar.

Cover thickness

Use the Cover thickness fields in the reinforcement properties dialog boxes to define concrete cover.

Reinforcement

76


Example

To create a beam stirrup, pick the corner points on the cross-sectional end plane of the beam to define the bar shape and plane. The cover thickness on the plane is the distance from beam’s bottom, top, and side surfaces to the stirrup. The cover thickness from the plane is the distance from the end surface of the beam to the stirrup, and perpendicular to the bar plane.

Concrete cover

Description Concrete cover on the plane For example, the distances from a beam’s bottom, top, and side surfaces to a stirrup. To specify different concrete covers on the different legs of a rei nforcing bar, enter a thickness value for each leg in the On plane field, in the order you pick points to create the bar. If you enter less values than there are bar legs, Tekla Structures uses the last value for remaining legs. Concrete cover from the plane For example, the distance from a beam’s end surface to the closest stirrup, perpendicular to the stirrup plane.

Leg length

At the start and end point of a reinforcing bar, you can also define the concrete cover in terms of cover thickness or leg length.

Option

Description Cover thickness

Defines the distance from the bar end to the concrete surface.

Leg length

Defines the length of the ultimate leg of the bar.

To define the length of an ultimate leg of a bar, use the Leg length option and the Snap to nearest points switch. Then pick anywhere on a part edge or line to indicate the direction for the bar leg.

Reinforcement components

When you use reinforcement components, Tekla Structures places the reinforcement using the dimensions of the part and the values in the Cover thickness field, or the graphic fields shown below:

Reinforcement

77


Spacing reinforcing bars Bar groups

There are several ways to distribute bars in a reinforcing bar group. To create a bar group, open the Reinforcing Bar Properties dialog box. On the Group tab, select an option from the Creation method list box. The options are:

Option

See also

Description

By exact spacing value with flexible first space

Creates fixed, equal spaces between the bars. The first space adjusts to even out bar distribution. Enter the spacing value in the Exact spacing value field. If the first space is less than 10% of the exact spacing value, Tekla Structures removes one bar.

By exact spacing value with flexible last space

Same as the first option, but the last space adjusts to even out bar distribution.

By exact spacing value with flexible middle space

Same as the first option, but the middle space adjusts to even out bar distribution. If there are an odd number of bars (two middle spaces), the other middle space adjusts to even out bar distribution.

By exact spacing value with flexible first and last space

Same as the first option, but both the first and last spaces adjust to even out bar distribution.

By exact spacings

Distributes the bars using the information you specify in the Exact spacing values field, so you can enter every spacing value manually. Use the multiplication character to repeat spacings, e.g. 5*200, to create five spaces of 200.

Equal distribution by number of reinforcing bars

Tekla Structures determines the spacing value based on the fixed number of bars. Enter the number in the Number of reinforcing bars field.

Equal distribution by target spacing value

Tekla Structures aims the spacing value as close as possible to the value in the Target spacing value field and determines the number of bars compatibly.

Omitting reinforcing bars (78)

Omitting reinforcing bars You may occasionally need to omit specific reinforcing bars. For example, when several reinforced areas intersect, causing reinforcing bars to overlap, or when you want to start bar distribution at a specific distance from the end of a part. To indicate which bars to omit, select an option from the Reinforcing bar(s) not to be created to the group list box: •

Reinforcement

79


•

Bent

Distribution You can create meshes with unevenly-spaced bars. You can also define a different bar size or pattern of bars multiple different bar sizes for the longitudinal bars and the crossing bars. Multiple bar sizes enable pattern creation. For example, if you enter bar diameters 20 2*6 in the longitudinal direction, Tekla Structures creates a pattern with one size 20 bar and two size 6 bars. This pattern can be repeated in the mesh along the longitudinal direction.

For more information, see Customizing reinforcement meshes (105).

Mesh size

The way you define the size of the mesh depends on the shape of the mesh and how it was created: •

The ends and corners of a reinforcing bar The distribution length of a bar group The corners and main bar direction of a mesh

When you select a reinforcement, the handles turn magenta.

Examples

Here are some ways to use handles to modify reinforcement:

Reinforcement

96


Handles to change group distribution length Handles to move bar corners

Handles to move mesh corners Handles to change main bar direction To use handles to modify reinforcement: 1. Select the reinforcement to display its handles. 2. Click the handle you want to move. Tekla Structures highlights the handle. 3. Move the handle(s) like any other object. If Drag and drop is active, just drag the handle to a new position. For more information, see Moving an object, Moving an object using drag-and-drop and Polygon cuts.

Using adaptivity Reinforcements follow the shape of the part also when their handles are located on the face or edge of the part. The following types of adaptivity are available: •

•

Fixed adaptivity: handles retain their absolute distances to the nearest part faces. Relative adaptivity: handles retain their relative distances to the nearest part faces in relation to the part’s overall size.

To modify the general adaptivity settings, go to Tools > Options > Options... > General. You can modify the adaptivity settings for each part separately. These modifications override the general settings.

Reinforcement geometry validity Reinforcement creation or modification can result in invalid reinforcement geometry. For example, too big bending radius can cause invalid reinforcement geometry. The invalid geometry is visualized in the model. Tekla Structures displays a warning message, and draws a thin line between the reinforcement handles to show the invalid geometry. You can correct the reinforcement geometry by selecting the line and modifying the reinforcement properties. You can check the reinforcement geometry validity by running the command Tools > Diagnose & Repair Model > Diagnose Model. The report lists the reinforcements with invalid geometry. If a model contains reinforcements with invalid geometry, the reinforcements are not shown in the drawings. The reinforcements become visible when the geometry is corrected.

Limitations

Reinforcement geometry validity check does not work with circular or curved reinforcing bar groups.

2.6 Reinforcing bar bending shapes in the Rebar Shape Manager You can define your own reinforcing bar bending shapes with the Rebar Shape Manager, and thus increase the amount of recognized reinforcing bar shapes. User-defined bending shapes are useful when Tekla Structures does not recognize the bending shape and assigns the UNKNOWN bending type to the shape. With the Rebar Shape Manager you can •

The Rebar Shape Manager is a tool for recognizing reinforcing bar shapes. You cannot control the reinforcing bar creation properties, such as cover thickness, reinforcing bar grade, or size, with this tool. The tool is meant for users who need to customize the bending shapes based on company or project requirements.

Reinforcing bar bending shapes in the RebarShapeRules.xml file When you define your own reinforcing bar bending shapes in the Rebar Shape Manager, an XML file called RebarShapeRules.xml is created in the current model folder. In addition, Tekla Structures installation contains by default an XML file called RebarShapeRules.xml. This file contains the most typical bending shapes of your environment, and it is located in the ..\Tekla Structures\\environments\\system folder. When you define new shapes, the shapes in the default RebarShapeRules.xml rule file can be appended to your own shapes. Tekla Structures reads valid RebarShapeRules.xml rule files in the model, firm, project and system folders, and merges the files. All the found bending shapes are displayed in the Rebar Shape Manager.

3. Select one unknown shape from the Model rebars list. 4. To define the needed information for a bending shape, do the following:

To define

Do this

Shape code

Enter a shape code for an unknown shape.

Bending shape rules

Add or delete a bending shape rule by clicking the Add and Delete buttons on the right. Use the Reset button to restore the original values.

Check hooks

Select the check box if you want to define different shape codes or bending schedule fields for two bars that otherwise have exactly the same geometry, but one bar has hooks and the other one does not. If you select the check box, hooks are considered as hooks. If you clear the check box, hooks are considered as normal legs. Note that the Check hooks option works independently from the advanced option XS_REBAR_RECOGNITION_HOOKS_CONSIDERATION, and it allows bars that have different hooks to have different shape code or schedule fields regardless of the value of the advanced option.

Update

Update the existing shape code definition of the selected reinforcing bar. You can update the definition if you have modified the shape code, bending shape rules or the contents of bending schedule fields.

Bending schedule fields

Define the content for a bending schedule. Right-click a field to select a bending shape property or to enter a formula. The names of the Bending schedule fields (A, B, and so on) are used in templates and reports. To make sure that old reports also work correctly, we recommend that you use the same DIM_XX fields as in the rebar_schedule_config.inp file.

5. When you have finished defining the new shape, click Add to add the bending shape definition to the RebarShapeRules.xml file. To enable the Add button you need to change the bending shape rule, enter a shape code or select the Check hooks check box. 6. Click Save to save the RebarShapeRules.xml file.

Reinforcement

109


By default, the file is located in the current model folder. When you create, for example, a bending schedule, Tekla Structures uses the updated bending shape information, recognizes the added bending shape and assigns a correct shape code to it.

The Rebar Shape Manager is able to recognize bending shapes regardless of the modeling direction of the bars. This means that the modeling direction has no effect on the shape definition and the shape code. When defining the bending shapes, the start or the end of modeling direction is always sorted based first on bending angles, then on twist angles, and finally on leg lengths. However, bending radius is not taken into account in the sorting. This means that radius 1 may not always be less than radius 2 or vice versa.

Bending angle between the legs. Bending angle is always between 0 and +180 degrees. The angle cannot be negative.

Twist angle (T)

The rotation angle of a plane that has been created by two bars of consecutive lengths. The plane is rotated around the axis of the last bar creating the plane. For bars where all the legs lie in the same plane, the twist angle is either 0 degrees or +180 degrees. If the bar twists out of the plane, i.e. the bar is in 3D, the twist angle is between -180 and +180 degrees.

Leg length (L)

Length of the leg.

Leg (V)

Leg direction as a vector value.

Leg distance from leg (D)

Similar to Point/arc distance off from leg (H). The difference is that Point/arc distance off from leg (H) considers the bending radius, whereas Leg distance from leg (D) is measured from the sharp corner. When the legs are parallel, both Leg distance from leg (D) and Point/arc distance off from leg (H) give the same result.

Bending schedule fields cell shows the result of a valid formula. If the formula is not valid, a question mark and text describing the error is shown.

Use the fields S, T, U or V to report angles. If you do not use these fields, you need to override the default unit settings in the Template Editor.

Example

Formula is L1+L3+L5-2*DIA •

•

L1, L3

and L5 are the leg lengths measured from outer edge to outer edge H1 is the total width to achieve H1: L1+L3+L5 minus 2*bar diameter

2.7 Reinforcing bar bending types Tekla Structures recognizes different reinforcing bar bending shapes and assigns bending type identifiers to them. The table below lists these reinforcing bar bending types. If Tekla Structures does not recognize the shape of a reinforcing bar, it assigns the type to it.

UNKNOWN bending

The bending type identifiers in the table below are internal, hard-coded types of Tekla Structures. The leg dimensions (D1, D2, etc.) and bending angles (A1, A2, etc.) of reinforcing bars are internal dimensions and angles. You can map internal types, for example, to country- or project-specific types, and internal dimensions and angles to specific template attributes. You do this in the rebar_schedule_config.inp file. See Reinforcement in templates (137). Reinforcing bar bending dimensions are calculated so that the leg dimensions (D1, D2, etc.) follow the outer edge, or the edge extension, of the reinforcing bar. The total length is calculated according to the center line of the reinforcing bar. The magenta points in the images represent the points you pick in the model when you create reinforcing bars.

Reinforcement in templates Audience

This topic is aimed at Tekla Structures users who need to localize reinforcing bar bending types or to create templates for reinforcing bar bending schedules.

Reinforcement You can show dimensions, bending angles, and bending types of reinforcing bars in drawings and templates reports by including reinforcement-specific attributes, such as DIM_A, ANG_S, SHAPE, and SHAPE_INTERNAL, in template fields. For more information on creating templates, see the Template Editor (TplEd) online help. Mapping dimensions

Use the rebar_schedule_config.inp file in the

..\Tekla

Structures\\environments\\system •

•

folder to map:

Tekla Structures internal reinforcing bar dimensions and angles with specific template attributes Tekla Structures internal reinforcing bar bending types with specific bending types

These mappings are environment-specific by default. You can modify them to suit your company or project needs. You can use equations, functions, and need to show.

if

statements to calculate the dimensions and angles you

Use any standard text editor (for example, Notepad) to edit the file.

Examples

rebar_schedule_config.inp

The following example of the rebar_schedule_config.inp file maps the internal bending type 5_1 to the bending type identifier E, and the leg dimensions and bending angles to specific template attributes:

rebar_schedule_config.inp (Example 1) BEND_TYPE_5_1[1]="E" BEND_TYPE_5_1[2]="DIM_A=D1" BEND_TYPE_5_1[3]="DIM_B=D5" BEND_TYPE_5_1[4]="DIM_C=D2" BEND_TYPE_5_1[5]="DIM_TD=TD" BEND_TYPE_5_1[6]="ANG_U=A1" BEND_TYPE_5_1[7]="ANG_V=A2"

With this mapping, the internal bending type 6_2 becomes XY, and the template attributes DIM_B and DIM_C will show the horizontal and vertical dimensions of the second leg D2, and DIM_E and DIM_F the horizontal and vertical dimensions of the fourth leg D4:

rebar_schedule_config.inp (Example 2) BEND_TYPE_6_2[1]="XY" BEND_TYPE_6_2[2]="DIM_A=D1" BEND_TYPE_6_2[3]="DIM_B=D2*COS(A2*PI/ 180)" BEND_TYPE_6_2[4]="DIM_C=D2*SIN(A2*PI/ 180)" BEND_TYPE_6_2[5]="DIM_D=D3" BEND_TYPE_6_2[6]="DIM_E=D4*COS(A1*PI/ 180)" BEND_TYPE_6_2[7]="DIM_F=D4*SIN(A1*PI/ 180)" BEND_TYPE_6_2[8]="DIM_G=D5" BEND_TYPE_6_2[9]="DIM_TD=TD"

The following example maps the internal bending type 4 to the bending type identifier A if the dimensions D1 and D3 are the same. Otherwise it maps 4 to B:

Reinforcement

138


rebar_schedule_config.inp (Example 3) BEND_TYPE_4[1]=if (D1==D3) then ("A") else ("B") endif BEND_TYPE_4[2]="DIM_A=D1" BEND_TYPE_4[3]="DIM_B=D2" BEND_TYPE_4[4]="DIM_C=D3" BEND_TYPE_4[5]="DIM_TD=TD"

If Tekla Structures does not recognize a reinforcing bar bending shape, it uses the internal bending type UNKNOWN for it. In the rebar_schedule_config.inp file you can also define how unknown bending types appear in drawings and reports. For example, you may just want to use the bending type identifier ???, and list all leg dimensions and bending angles:

rebar_schedule_config.inp (Example 4) BEND_TYPE_UNKNOWN[1]="???" BEND_TYPE_UNKNOWN[2]="DIM_A=D1" BEND_TYPE_UNKNOWN[3]="DIM_B=D2" BEND_TYPE_UNKNOWN[4]="DIM_C=D3" BEND_TYPE_UNKNOWN[5]="DIM_D=D4" BEND_TYPE_UNKNOWN[6]="DIM_E=D5" BEND_TYPE_UNKNOWN[7]="DIM_F=D6" BEND_TYPE_UNKNOWN[8]="ANG_S=A1" BEND_TYPE_UNKNOWN[9]="ANG_T=A2" BEND_TYPE_UNKNOWN[10]="ANG_U=A3" BEND_TYPE_UNKNOWN[11]="ANG_V=A4" BEND_TYPE_UNKNOWN[12]="DIM_TD=TD"
