摘要
以某连续刚构桥为工程背景,运用了大型专业有限元结构分析软件Midas Civil建立动力分析模型,并进行了模态分析。在此基础上采用动力反应谱分析法和动力时程分析法分别计算了结构的地震响应,并对两种结果进行对比分析,所得结论为大跨度连续刚构桥的抗震分析和设计提供相关依据。
Taking the continuous rigid frame bridge as the engineering background,this paper uses finite element analysis software,Midas Civil,to establish the model of dynamic analysis and make the modal analysis.On the basis of this,this paper adopts the response spectrum method and time history analysis method to calculate seismic response of the structure respectively and compares and analyzes the results of the two methods,and the conclusions can provide relevant basis for seismic design of the long -span continuous rigid frame bridge.
