A modal pushover analysis procedure for estimating seismic demands for buildings
Anil K. Chopra,Rakesh K. Goel +1 more
TL;DR: In this paper, an improved pushover analysis procedure based on structural dynamics theory, which retains the conceptual simplicity and computational attractiveness of current procedures with invariant force distribution, is presented. But, the MPA procedure is not accurate enough for practical application in building evaluation and design.
