15. From the Assign menu select Frame and then Releases… from the submenu. This will display the Frame Releases dialog box. 16. In this dialog box: Check the End box for Moment M22 (Minor) and Moment M33 (Major). Click the OK button to apply the releases. 17. The member end releases have now been corrected. Click the Set Elements button on the main toolbar (or select Set Elements… from the View menu). This displays the Set Elements Dialog box. 18. In this dialog box uncheck the Local Axes box and the Labels box in the Frames area and click the OK button. 19. From the Select menu select Select and then Groups… from the submenu. This will display the Select Groups dialog box. 20. Click on the group name BRACE1 once to highlight it, then, holding down the Ctrl key, click on the Group Named BRACE2 to add it to the selection. Click the OK button. 21. From the Assign menu select Frame and then Releases… from the submenu. This will display the Frame Releases dialog box. 22. In this dialog box: Check the Start and End boxes for Moment M22 (Minor), Moment M33 (Major) and the Start box for Torsion. Note: You can apply a torsional release at one end of the frame element or the other, but not both simultaneously. If you applied a torsion release to both ends, the frame element would be free to spin about its longitudinal axis, and thus the structure would be unstable. Click the OK button to apply the releases. 23. From the Assign menu select Clear Display of Assigns to clear the display of frame releases from the plan view. 24. Click the Save Model button on the main toolbar, or select Save from the File menu to save the file. This completes the assignment of frame element end releases. SAP2000 Web Tutorial 1 50
Step 10: Defining Static Load Cases We will define five static load cases. They are dead load, live load, earthquake in the X- direction, earthquake in the Y-direction and a load pattern to be used in the pushover analysis. 1. From the Define menu select Static Load Cases…. This will display the Define Static Load Case Names dialog box. 2. In this dialog box: • Type DL in the Load edit box. • Select Dead from the Type drop-down box. • Type 0 in the Self Weight Multiplier edit box. • Click the Change Load button. Note: In this example, if we had wanted the program to automatically include the selfweight of the structural members, we would have specified a non zero weight per unit volume in the Material data, and we would have put a self-weight multiplier of 1 on the DL load case only. • Type LL in the Load edit box. • Select Live from the Type drop-down box. • Type 0 in the Self Weight Multiplier edit box. • Click the Add New Load button. • Type EQX in the Load edit box. • Select Quake from the Type drop-down box. • Type 0 in the Self Weight Multiplier edit box. • Click the Add New Load button. • Type EQY in the Load edit box. • Select Quake from the Type drop-down box. • Type 0 in the Self Weight Multiplier edit box. • Click the Add New Load button.
