Past earthquakes illustrate the damages due to irregularities in building configuration. Since structural system of building configuration should be confirm to earthquake resistant. The approach of design of Multistory building should be based mainly on lateral stability and deformation in static analysis because as per Bureau of Indian standard actual forces much higher than design forces during earthquake. The aim of present study is to access the lateral stability of multistory building subjected to seismic forces with different geometric plans (square, circle, equilateral triangle) under different configuration having same plan area. Further analysis is done by equivalent static method. The percentage drift and storey deflection due to seismic forces are calculated for different models having same plan area. By this above study it was found that the optimum values for storey drift and deflections are for circular shape model.

Keywords: Multistory building, Equivalent Static method, storey drift and deflection.
