A STUDY ON INFLUENCE OF MASONRY INFILLS AND SHEAR WALL ON THE SEISMIC PER FORMANCE OF R.C FRAMED BUILDING

The study offerings the practice for seismic performance estimation of asymmetric reinforced concrete frame buildings through ground soft storey built on a perception of the capacity spectrum method. Previous recent seismic tremors in many parts of India and globe have discovered the issue concerning the weakness of present structures. The present structures, which were designed and constructed based on earlier code requirements, do not content requirement of current se ismic code and design practice. “ETABS” is used as a structural analysis tool for analyzing building models . Mainly which effect the mass, strength, stiffness and deformability of the structure & other important components which influence the above properties of the structures includes in analytical model of the building. To study the effect of infill and concrete core wall & shear wall at different positions during earthquake, seismic analysis using both linear static, linear dyn amic (response spectrum method) as well as non - linear static procedure (pushover) has been performed. It is an attempt to study the performance of multistoried reinforced concrete building frame due to influence/provision of masonry infill’s and shear wall, five (5) building models (11 storey each) with identical building plan and asymmetry in elevation were study and analyzed. By performing Equivalent static, response spectrum method the deflections at each storey level has been compared as well as to determine capacity, demand and performance level of the considered building models the pushover method is adopted.
