Abstract

The masonry infill RC frames are the most recurrent type of structural element used in multi-storey constructions due to factors such as significant lateral stiffness, strength and overall ductility. With suitable adaptations to provide reinforcement in the masonry, it should be possible to also improve the seismic response of such infill.The following study is conducted to investigate, analyze and compare the response of RCC structure i.e., with masonry infill and without masonry infill, subjected to earthquake loading. The analysis is conducted on a G+5 structure with the loading condition given in Indian Standard IS1893:2002 codal provisions incorporating ETABS[9] software. The analysis is studied under the categories like pushover curve, storey displacement, storey shear at base, and storey drift.Results obtained from the analysis of structure with and without infill masonry walls shows that all the parameter discussed above, except storey shear, have a significant reduction for structure with infill wall which would result in over estimation of seismic influence on structure that could considerably optimize the seismic behaviour and sustainable impact of building on the environment.
