泉州火车站站前大桥桥头堡抗震性能研究

泉州火车站大桥桥头堡的造型新颖,属于特别不规则的结构,必须按《建筑抗振设计规范》,对抗震性能进行研究。基于大型有限元软件ANSYS,通过模态分析、地震反应谱分析、弹性动力时程分析,研究结果表明:在多遇地震作用下,该结构的位移较小,能够满足规范对该类结构的地震位移限制。

Study on Seismic Behaviors of the Bridgehead of Quanzhou Railway Station Bridge

The bridgehead of Quanzhou railway station bridge should be designed according to Code for Seismic Design of Buildings, because of its new type and irregular structure particularly. Based on the general finite element software ANSYS, model analysis, response spectrum analysis and elastic dynamic time-history analysis were conducted on the bridgehead of Quanzhou railway station bridge. Results showed that the lateral displacement of the structure was small under frequently occurred earthquake and it was less than the limit value in the code.
