## Scaling of Base Shear in ETABS

Seismic base shear computed from modal response spectrum analysis should be scaled to a minimum percentage of the static base shear.

This post presents the procedure in scaling of base shear in ETABS. It is assumed that you are already aware of the principles of response spectrum analysis and are using CSI ETABS as your analysis tool. UBC-97 and ASCE 7-05 or later require that the base shear calculated using modal response spectrum dynamic analysis should … Read more about Scaling of Base Shear in ETABS
