Seismic Performance Assessment Of Rcs Building By Response Spectrum And Pushover Analysis

Abstract

Hybrid RCS frame system integrates reinforced concrete (RC) columns with structural steel (S) beams, combining the advantages of concrete and structural steel. Past studies have shown better performance of RCS structure in comparison to pure steel and conventional concrete system. Despite the past research, the use of steel in construction industry in India is very low as compared to many developing countries. The RCC Structure is no longer suitable because of increased dead load and stiffness. There is great potential for increasing volume of steel in construction. The main aim of the present work is to evaluate the performance of RCS system in severe seismic zone and facilitate the greater acceptance and use of RCS systems as an alternative to conventional lateral resisting systems in comparison with ordinary RCC building. Fifteen story regular and irregular RCS and RCC frame buildings are designed according to IS Codes of practice and analysed using - SAP2000. Response spectrum and pushover analysis are carried out to assess the seismic performance of RCS building and compared with equivalent RCC structure.
