Abstract

P-delta effect is a secondary effect on structure, also known as ‘Geometric nonlinearity effect’. With increaseinnumber of stories, P-Delta effect becomes more important. If the variation within bending moments anddisplacements is more than 10%, P-delta effect should be considered in design. In this study, high rise buildingisstudied and both, linear static analysis (without P-delta effect) and second order analysis (with P-delta effect) onhigh rise building having different number of stories have been carried out. Building models with different storeyheights have been analyzed to investigate the maximum response in the building in terms of displacement, drift ratio, moment and shear forces. The analysis of multistoried RC building have been done using ETABS 2015 Ver. 15.2.0structural analysis software.
