Seismic performance of RC plane frame building Irregular in Mass

Abstract

With increase in urban infrastructure, irregularities in buildings are increasing. These irregularities are results of aesthetic and functional needs. Past research works give clear difference between seismic response of regular and irregular building configurations. Seismic analysis and design of 10 storey Reinforced Concrete (RC) Moment Resisting Frame building is given in this paper. Vertical irregularity in terms of mass variation is present. Indian codes of practices are used for the modelling and analysis of building such as IS 1893(Part-1):2016 and IS 456.  Linear static, linear dynamic and nonlinear time history analysis are used to get seismic response. Twenty-three earthquake ground motions have been used. Evaluated results such as displacement, storey drift, inter storey drift and storey shear are compared with regular building having similar configuration.
