Export to Esteem v5.2
This command is only applicable to user with EsteemWin v5.2 . This command allows user to transfer the beam results to EsteemWin v5.2. Currently, EsteemPlus v6.X does not support T-beam section design. However, user can use EsteemWin v5.2 to redesign the beam section. Valid beams design results will be exported to Esteem Win v5.2 for analysis.
Reminder
: The beams results from EsteemWin v5.2 cannot be
incorporated back into Esteem Plus v6.*. The results and the details of the beams will be independently generated in Esteem Win v5.2.

Project Reset Project Analysis Result
Selecting this command resets all your current project analysis results. Any analysis results performed will be permanently deleted. You will not be able to retrieve the results once you selected this command.
Note
: This command is useful when you have trouble
assessing the project. When the program performs analysis and stalls during analysis. The analysis is incomplete and the results data would become corrupted or invalid. Clearing the corrupted results would allow you to assess the project.
Check Project Grid Integrity
This command allows you to check the grid integrity of the whole structure. The program performs integrity check for any grid discrepancy between each floors of the structure. The program reports gridlines with any discrepancy. discrepancy.
Grid discrepancy occurs when two or more gridmarks between floors that do not match. For example gridmark B of floor GB is 4000mm from gridmark A while gridmark B of floor 1B is 4100mm from gridmark A. The inconsistency in dimensioning of the same gridmark B in different floors creates grid discrepancy.
You cannot have different name for the same gridline position in different floors. The program detects this discrepancy in grid integrity check. For example, for the same position of gridlines, you named gridline on floor GB as gridmark A. However on floor 1B, you renamed the same gridline as gridmark A1. This is not allowed and the program reports discrepancy in this particular case.

Check Project Integrity
Using this command initiates the program to check for the global structural integrity. Any warnings detected will prevent any further analysis until problem is resolved. The program highlights the element that contains error. The program performs checking on the following area:
Check transfer column: The program checks for valid transfer column in the model. Transfer column can be supported only by beam or wall.
Check for column: The program does not allow column offset from the position out of the column area above or below it. The program does not consider eccentricity into column design. However in column design, moment due to minimum eccentricity will be checked by the program.
Check for wall: Detects any created wall for every floor.
Check for wall opening: Detects any wall opening for every created wall.
Check rc wall overlap: Detects any overlapping walls.
Check rc wall opening overlap: Detects any overlap opening in the same location. If wall openings overlapping detected, the program automatically delete the later created wall opening.
Check wall data for individual floor: Performs checks on the validity and consistency of data for wall.

Pin foundation: Checking this option set the all columns bottom condition at foundation level to be pin restraints during 3-D analysis. This is not applicable for shearwall that acts as vertically cantilevered beam from the ground. Disable this option will not create a valid design for foundation designs in later stages. Currently, this program does not support moment design for foundation.

Slab diaphragm effect: Selecting this option considers the slab effect into the frame analysis. The lateral loads acting on the structure will be transfer horizontally throughout the floor slab to the main lateral resisting element.
Double precision in analysis: Checking this option allows the program to perform more iterations in equation solving to provide more precise results. However more resources are used to perform this analysis and this might affects the performance of your computer.
Ground Floor Non-Suspended Slab: Enabling this option assumes that non-suspended slabs at ground floor provide restraints to the column. The program considers this effect and determines the effective height of the column. Disabling this option allows the program to determine the effective column height based on restraint conditions. This is only applicable when there are only slabs (without beams) connected to the column at ground floor.
Note
: This option does not affect the slab design at ground floor. For non-
suspended slab on ground floor, simply do not create any slab on this floor.

Creating Gridlines
Figure 7.1 : Example of creating gridline
You can create grid line from any reference grids in the same direction. You can rename the grid to your preference by clicking twice on the grid label and type in the grid mark. You can also modify the dimension of the grid by clicking twice on the dimension label at the bottom grid and type in the new dimension.
Note
: If you want to edit the dimension of the major gridline
with minor gridlines in between, you have decrease the indent of the minor gridlines before editing the dimension. The new dimension specified actually begins on the previous gridline. The program cannot differentiate between major and minor gridlines.
For example, you have gridlines labeled A, A1 and B. Grids A1 and B are located 1000mm and 4500mm respectively from grid A. Grid A1 is a minor gridline. Refer to figure 7.2 to 7.5 for further information. You want to change the dimension of Grid B 5500mm from Grid A. Double click on the dimension at the bottom grid and specify 4500mm. This is because the dimension of Grid B begins from grid A1 and not from grid A. If you modify Grid B dimension to 5500mm, the final dimension of Grid B from Grid A is actually 6500mm from Grid A.

Figure 7.5: To achieve Grid B 5500mm from Grid A, the dimension should be input as 4500mm instead of 5500mm
If you create a new gridline to the left direction from the initial gridline, the program will name the new gridline based on the last defined gridline. You have to change the grid mark manually in table properties if you prefer another grid mark label. For example, starting y-direction grid line mark is labelled as A and the last gridline you 7-118
Creating Gridlines
have defined is labelled as E. If you create a new gridline to the left from grid mark A, the grid mark will be label as F.
Tips : Create major grids first and add the minor grids later. This creates a regular naming to the labels of the grid lines.
Note
: The distance between 2 grids must be more than 300mm.

Using grid generator
Clicking Batch X Grid Input button brings up the multiple grid input form as shown in figure below where you can specify the number of grids of your choice. All dimensions are in millimeters,mm.
Figure 7.6: Multiple Grid Input
To enter multiple grids with different dimensions, specify the grid dimensions followed by the comma. This will generate the grids based on your specified input.
If the grids are symmetrical, input the dimension followed by 'x' and the number of grids you which to input. The program will duplicate the dimension to the proceeding number of grids defined.
You can also use the combination of the above methods to create the grids.
For example suppose you have 3 grid lines with dimensions of 3500mm,4500mm and 6000mm respectively in the x-direction. Thus input 3500,4500,6000 in the x-direction grid form. You have 10 grid lines with dimensions of 4500mm respectively in the y-direction.

table on the right side of the window. Input dead load and live l oad in the specified form. The units for UDL is kiloNewton per meter (kN/m). Move the cursor to the beam and the cursor changes to UDL icon. Click on the beam once to lock on the selected beam. An active box displays the position of the starting point of the UDL either from the bottom or left of the grid. Move the cursor to select the UDL starting position. To define the starting point of the UDL, move the cursor to the specific distance and click once. The active box then displays the distance for the UDL end point. To select the end point, click on the left button once.
Note
: Uniform Distributed Load, UDL always offsets from the
left or bottom of the grid.
For example, you have a two span beam separated by grid A, B and C with 3000mm and 4000mm respectively . You want to create a 5 kN/m uniform distributed dead load starting from 2000mm and ending at 4000mm from grid A. Select Input Beam UDL command and define 5kN/m dead load in the table properties. On the selected beam, move the cursor 2000mm from grid A and click once to define the starting point. Move the cursor 1000mm from grid B to select the ending point. Click on the left button once to select. Once created, you can see the UDL magnitudes and positions of the UDL on the key plan layout. By default, the UDL is indicated as red color hatch on the key plan layout as shown in figure 3. You can change the hatch color to your preferences, by selecting layer settings command.

General Variable Load
You can create non uniformly distributed load such as trapezoidal and
triangular
load
using
General Variable Load, GVL
command. To create general variable load, click GVL command to activate the load magnitudes table. There are 4 entries in the load magnitude section as shown in figure 8.10. The first dead and live load start from the left or bottom of the grids while the second dead and live load end the loads. You can modify any created loading positions using the load position table.
Figure 8.10: Load Magnitude Table Input
Warning
: You cannot leave load magnitude entries blank. This
generates an infinite value and will create error to the program. Set the entry to zero instead of leaving it blank. To create different type of loading patterns, you have to specify the load magnitudes accordingly as shown in figure x. In the figure below, X and Y represent the load magnitudes respectively and 0 represents zero/nil. Type 1 and 2 are triangular loads while type 3 and 4 are trapezoidal loads.

Esteemplus
Figure 8.11: Type of variable loadings
For example, you have 2 continuous span beams of 3000mm and 4000mm respectively marked by grid A, B and C. You want to create a 2000mm triangular load, 4000mm from grid A. From left side, the triangular dead load increases from 0 to 5 kN/m. Click on the GVL command and input 0 and 5 in the first dead load and second dead load entries respectively. Since there is no live load, input 0 to both first and second live load entries.
Select the beam by clicking once and move the cursor 2000mm from grid A. Click once to define the starting point of the triangular load. Move the cursor 4000mm from grid A. Note that when the cursor moves further than the beam spanning between grid A and grid B, the dimension display resets and begins at grid B.

Beam Offsets
You can offset the beam to flushes with the column. To offset a beam, select the particular beam and specify the figure in the Position table on the right of the window. Left click or press Enter to confirm the changes made. The beam offset is based on the center of the gridline. Input negative figure shifts the beam to the left/bottom of the gridline and positive figure shifts the beam to the right/top of the gridline.
You can offset the beam using the offset wizard. These features can automatically offset the beam to the left, right, top, bottom and center of the grid. Figure below shows the description of each offset commands.
Table 8.1: Beam offset commands
Beam to beam offset
When you offset the beam located perpendicular to a beam, the actual position of the beam is updated to the perpendicular beam. For example, you have two beam, primary beam GB1 and secondary beam GB2. Primary beam GB1 spans 5000mm from Grid A to Grid C. Secondary beam GB2 is positioned along Grid B. Grid B is located 2500mm from Grid A. Secondary beam GB2 without offset,
8-137
Esteemplus
is 2500mm from Grid A as shown in figure 8.16. If you offset beam GB2 100mm to the right of Grid B, the program automatically recognizes GB2 position at 2600mm from Grid A as shown in figure 8.17.
Figure 8.16: GB2 offset 2500mm from Grid A
Figure 8.17: GB2 offset 2600mm from Grid A
Beam to column offset
This option allows you to offset beam from the column. If you have beam offset from the column, the actual position of the beam is still located at the center of the column. The program will not incorporates the offset eccentricity to the column analysis. This beam to column offset function is merely for graphical purposes only.
