Abstract

Abstract

In the traditional Pushover method,the vertical earthquake effect,which has an impact on horizontal displacement,is not taken into consideration.When the seismic intensity in vertical direction takes a high ratio,it is hard to accurately estimate the maximum displacement demands on structure by the traditional Pushover method.Hence,the paper aims at making improvement on the traditional one.Firstly,the inertial force caused by vertical earthquake is enforced on structure according to certain means.Then,the multi-mode Pushover analysis procedures are applied in the horizontal direction of structure,and the maximum displacement demand is calculated on the ground of SRSS method.A multistory concrete frame is applied to testify this theory.The data shows that,using the improved method,the numerical results of floor displacement and story drift ratio are well agreed with the results from nonlinear time-history analysis,which demonstrated that the improved method is of high accuracy.
