Masonry infill is generally considered as non structural element. Structures with brick work infill wall in RC buildings generally increase stiffness and strength of the frame structure. The infills are normally not considered in the design of buildings as they are designed as bare frames. This study investigates the effect of masonry infill wall to check non linear behavior of RC frame building. For this purpose, Three RC frame buildings of G+20 i.e. regular building and buildings with vertical irregularity are considered (with bottom story considering as soft story/open story). For modeling masonry infill wall the equivalent diagonal strut approach is adopted. Displacement v/s base shear curves (pushover curves) are obtained for the structures using ETABS Nonlinear version 2016 software. To obtain pushover curves, Non linear analysis is carried out and results are presented in comparison with bare frame and with infill wall frame with soft story or open story. From the pushover curves, story displacements, inter-story drift, base shear are determined.
