多跨城市立交桥抗震性能研究
Research on anti-seismic performance of multi-span urban overpasses
【摘要】 以三跨T形宽桥面城市立交桥为工程背景,利用Midas Civil空间有限元分析软件建立结构有限元动力分析模型,并对该桥的地震响应和抗震性能进行了分析,为同类桥梁的抗震设计提供了参考依据。
【Abstract】 Taking the three-span T-shaped urban bridge overpasses as the engineering background,the paper adopts the spatial finite analysis software,Midas Civil,to establish the structural finite dynamic analysis models,and analyzes the seismic response and anti-seismic performance,so as to provide some reference for the anti-seismic design of similar bridges.
