Abstract:

Seismic codes are unique to a particular region or country. These take into account the local seismology, accepted level of seismic risk, building typologies, and materials and methods used in construction. They are indicative of the level of progress a country has made in the field of earthquake engineering. In this present paper, an investigation has been carried out to examine the behaviour of an existing Reinforced Concrete frame structure located in the four different seismic zones of India using nonlinear static analysis. The analysis of the structure has also been taken into account when designed with different diaphragms with and without infills. Study of the literature is reviewed in this paper on various techniques as; slabs are modeled as shell element, membrane with rigid diaphragms, membrane with semi rigid diaphragms and without any diaphragms. The results obtained by this analysis in terms of pushover curve, capacity spectrum and performance points are evaluated to check the performance of the structure with different diaphragms and with and without considering the stiffness of infills with different diaphragms.
