Application Of Performance Based Seismic Design Method To Reinforced Concrete Moment Resistant Frame With Vertical Geometric Irregularity With Soft Storey

摘要

A performance-based seismic design (PBSD) method is aimed at controlling the structural damage based on precise estimations of proper response parameters. PBSD method evaluates the performance of a building frame for any seismic hazard, the building may experience. Use of this method for vertical irregular buildings is verified with comparison of conventional method. Soft storey is subjected to failures due to stiffness and strength reduction. This paper deals with application of Performance based seismic design method for soft storey RC building frames(10 storeys) . Push over analysis results show significance of PBSD method in frames having soft story at lower floor level compared to higher ones.
