摘要
新开河大桥是新建京津城际铁路上一座典型的(48+80+48)m预应力混凝土连续箱梁桥,位于7度地震区.用自编程序,输入安评地震波对其进行了罕遇地震下的弹塑性地震反应分析,研究结论可供抗震设计参考,研究方法可供同类研究参考.
The Xinkai River bridge is a typical bridge of the new-built Jing-Jin city railway,which is a continuous bridge locating in the earthquake region with the main span of 48:80:48.In this paper,the elasto-plastic seismic analysis of the bridge is performed by using the self-programming and the exclusive waves.The conclusion of the bridge and the research technique can be the reference to the designer and the homogeneous research.
