STAAD.Pro and RAM Connection Link ®
™
INTRODUCTION Bentley’s STAAD.Pro V8 i and RAM.Connection have joined orces to now provide STAAD® customers the acility to design structural steel connections in an integrated environment. Once the steel structure has been analyzed and designed using STAAD.Pro, member proles and design orces can be automatically be exported out to RAM.Connection to design connections. The user will be able to view connection design results in the STAAD interace. RAM.Connection can currently design connections as per the AISC ASD, LRFD and the new 13th edition unied code. The STAAD.Pro and RAM.Connection link currently only supports connection design as per the AISC ASD and LRFD code. Figure 1 - 3D View of a Building Structure
RAM.Connection (ASD) The user will be able to design amilies o connections including: beam-to-column fange, beam-to-column web, beam-to-girder, beam-to-beam, column splices, beam splices, column-beam-brace gusset connections, chevron brace connections, X brace connections and brackets.
1. Open the WHBuilding-Bracing.std le in STAAD.pro V8i. 2. Run the analysis using the Analyze > Run Analysis menu command.

4. In this exercise, we will try to design a connection or column 334 and beam 197 as shown in Figure 2. 5. Press the New Envelope button located on the bottom right hand side corner o your screen. Using this eature, you will be able to speciy the loads that are to be used or the connection design. 6. In this model, we have generated the load combinations using STAAD.pro automatic AISC load generator. We would like to use all the load combinations or the connection design. Thereore click on the Show Load Combinations Only and Select All Load Cases Shown Below check boxes. Figure 3 - Creation of the load envelope
7. Click on the Ok button. On the right hand side o the screen, Design Envelope 1 tree item will be created under the Envelope tree item. 8. Select Beam 197 and column 334 as shown in Figure 2 using the mouse and pressing and holding the CTRL key on your keyboard.
Figure 4 - Joint dialog box
9. Click on the Create Joints button on the right hand side data area. The Joint dialog box will appear and will list the column and beam number and set the joint type to BCF. You need to veriy i this inormation is correct. In our model, we are designing a Beam-to-column lange connection so this inormation is correct. Please reer to section AD.2007-1001.5.1 AD.2007-1001.5.1 RAM Connection Design Mode in the STAAD.Pro help documentation or a list o connection types that are supported. 10. Click on the Ok button. Note that a grey colored triangle will appear in the STAAD.Pro graphics window indicating that you have created a joint. Please reer to section AD.2007-1001.5.1 AD.2007-1001 .5.1 RAM Connection Design Mode in the STAAD.Pro help documentation or joint color coding scheme. The grey color simply indicates that no Design Brie has been associated to the joint.

Note that in the data area, the J1-BCF entry has been created in the Joints tree item. 11. Click on the Create Brie button located in the data area. The Design Brie dialog box will appear. Note that the user may select any load envelope that he/she has created. 12. Select the AISC-ASD code. Note that the Design Connections Individually button has been checked o. I this button is check on, STAAD.Pro will assign dierent connection conigurationss to dierent joints included in coniguration the same brie. Figure 8 - Joints Cursor

13. Select the Basic SP BCF (i.e. Shear Plate, Beam to Column Flange) connection in the connection selection box. The basic connection allows the user to speciy a connection or a joint or speciy a group o connections to a joint. STAAD.Pro and RAM. Connection will pick the one that is suitable or the group o connections connections.. I the Smart connection type is selected, RAM.Connection RAM.Connection will create a connection rom scratch and suggest an optimum connection. In this exercise, the Basic SP BCF will be assigned. 14. Transer all the connections rom the let hand side to the right hand side using the double arrows pointing towards the right. 15. Press the Ok button. Note the B1: Design Brie 1 tree item is created in the data area. 16. Select the Joints Cursor on the let hand-side o your screen. Figure 9 - Connection Design Dialog box
17. Select the B1: Design Brie 1 in the data area. 18. Select the Assign to Selected Entities option in the data area. 19. Press the Assign button. 20. You have successully deined the connection design parameters. To design the connection using RAM.Connection, RAM.Connection, click on the graphics window in the white area and then click on Connection Design > Design All Connections menu command. The connection design dialog box will appear showing you the status o the connection. 21. Click the Done button. 22. Select the Joints Cursor on the let hand-side o your screen. 23. Double click on the BCF connection.
