Abstract

The lack of infill in multi-story buildings in urban India, particularly on the ground floor or other floors for purposes such as parking or open storefronts, can result in vertical stiffness irregularity and make the structure more vulnerable to earthquakes. The practice of incorporating open first stories in seismic active areas is widely regarded as undesirable due to the risk of building collapse during earthquakes. With advancements in computer technology and the rise of performance-based seismic engineering (PBSE), it is now possible to simulate the expected performance of a structure under seismic forces. PBSE integrates seismic hazard assessments with inelastic structural analysis to determine the structure's expected seismic performance. This is typically achieved through nonlinear static analysis, also known as pushover analysis.Keywords: Reinforced concrete, open ground storey, RC frames, nonlinear static analysis, performance assessment, evaluation, capabilities.
