| Abstract: | By analyzing and summarizing the seismic damage of double column bridge with high-rise piers,it is believed that collar beams designed between double column high-rise piers have great influence on the strained condition of substructure suffered from earthquake action.SAP2000,one of finite element softwares,was used to perform modal analysis and response spectrum analysis for a 30 m long double columns high-rise pier continuous beam bridge.The number,location and section dimension of collar beam which have i... |
