You should have a look at Display -> Show Tables -> Modal Information -> Table: Response Spectrum Base Reactions. They have had to introduce a special routine to determine base reactions since all results from Response Analysis are positive. Summing base reactions or column shears would...
Has anyone verified the results of the P-Delta analysis. Our code (CAN)requires two checks, first actual loads and second notional loads. Looks like ETABS is only doing second.
Changes to a design model, such as shear wall location, were time consuming to make in earlier versions of ETABS. How does the current version of ETABS fair in this regard? Are changes made as the design process progresses easy and quick to make?
CSI have an article "SAFE Technical Note 1" entitled "How SAFE Calculates Punching Shear For the ACI 318-95 Code". This article can be downloaded from the CSI web site.
