General Analysis Criteria

Before performing the analysis you should always establish your criteria using the Criteria menu. To set the general analysis criteria:

Set Rigid End Zones to Include Effects and Type 50 for Reduction %. This means that the beams in the rigid frames will be shorted in the analysis to the face of the column.
Set Member Force Output to At Face of Joint (when using rigid end zones you have no choice).
Set P-Delta to Yes and Type 1 for Scale Factor. This means that second-order, P-Delta effects will be calculated for all load cases utilizing the building mass Dead Load as the P in the P-delta calculations. If you wanted to also consider part of the Live Loads in the P-Delta calculations, then you can increase the value somewhat.
Check the Use Reduced Stiffness for Steel Members checkbox, and click on the τ_b = 1 radio button.
For the Wall Mesh set the Max. Distance Allowed between Nodes to 8 (2.5). This means that the program will mesh the walls in such a way that no single element is more than 8’ on a side (though they may be smaller due to geometric constraints). More Mesh options are available by clicking the [Advanced] button.
Check the Store Wall Stresses checkbox for use in the Concrete Shear wall module.
Click [OK].
