Abstract

Abstract

In the procedure of modal pushover analysis,non-linear time-history analysis is not so operative and its analytical result is unstable,the capacity-spectrum theory is used to take the place of dynamic time-history anslysis.Converting the acceleration response spectrum of current code into displacement response spectrum,the displacement response of equivalent single degree of freedom in each mode of vibration can be calculated by capacity spectrum method.Then the displacement response of multi-degree of freedom can be obtained too,and it is used to compare with the corresponding displacement(storey drift ratio) limits,judging whether the structure satisfies its performance objective or not.The proposed method improves the modal pushover analysisoperation and stability.
