SEISMIC ANALYSIS OF RCC BUILDINGS WITH AND WITHOUT MASONRY INFILLS

Abstract

The presence of infill in reinforced concrete structure can extremely affect the response of structure under seismic loads. There might be a positive effect due to increase of strength and stiffness but the drawbacks start to appear due to stress concentrations. The codes have limited information on the design of infilled structures besides different architectural requirements which increases the problems. Pushover analysis was performed on the structure to study the influence of infill on the performance of RCC structures. The results show that the influence of infill on the structural performance is significant. The structural response such as fundamental period, roof displacement, inter story drift ratio, stresses in structural member reduces with the incorporation of infill.
