Seismic Performance Evaluation of Setback Building with Open Ground storey
Journal Title: GRD Journal for Engineering - Year 2019, Vol 4, Issue 0
Abstract
This study investigates the performance of the setback building with open ground storey using nonlinear static pushover analysis. Such type of building possess vertical geometric and mass irregularity as well as stiffness irregularity. In this paper, plan irregular setback building with open ground storey resting on plain and sloping ground which makes the building so weak to survive during earthquake. An attempt has made to alleviate effects of these irregularities during earthquake by replacing OGS columns by Reinforced concrete filled steel tube columns. RCFST columns increases the stiffness of the OGS which offset the soft storey effect as well as reduce storey displacement, drift and torsional response significantly. From hinges results, it can be observed that performance of the building is improved significantly.
