3D Numerical Analyses of Seismic Behavior of Changshan Long Span Extradosed Cable-stayed Bridge
摘要
Abstract
With the aim of further understanding of dynamic response characteristics of extradosed cable-stayed bridge,a large scale three-dimensional numerical model is established by considering pile-soil interaction and effects of pre-stressed rebar based on ADINA under the engineering background of the Changshan bridge.Furthermore,three dimensional numerical analyses with earthquake response spectrum method and elastic and elasto-plastic dynamic time-history methods are employed and the seismic performance of the whole interaction system of bridge is evaluated.The numerical results show that deformation and strength at control sections meet the requirements of the code for seismic design of bridge,and considerable plastic deformation may occur at main piers.Thus,elasto-plastic deformation check at control sections of structure should be performed for seismic design of extradosed cable-stayed bridge.关键词
