Study of Effect of Eccentricity on the Linear and Nonlinear Behaviour of RCC Irregular Buildings

This paper discusses the complex behaviour of asymmetric structures; a study on the influence of variation in eccentricity due to mass asymmetry (using different magnitudes of asymmetry and different magnitudes of mass) on the linear and nonlinear behaviour of structure using response spectrum and static pushover analysis. The study is done using ETABS 9.7.4 software. The study concludes that increase in eccentricity, mainly increases the torsion due to seismic forces and does not have significant effect on the lateral displacement of the structure. This increase depends on both the magnitude of mass and the magnitude of asymmetry.
