Great span continuous rigid frame bridge piers earthquake response analysis

摘要

In order to analyze the form of piers span continuous rigid frame bridge seismic impact on the order of a continuous rigid frame bridge engineering background, the use of large-scale professional finite element analysis software MIDAS CIVIL build dynamic analysis models were different cross-sectional forms modal pier analysis, using dynamic response spectrum analysis method to calculate the dynamic response of the structure, and comparative analysis of different results, the conclusions of large span continuous seismic analysis and design of the bridge just enough to provide relevant basis.
