装配式连续梁桥抗震性能分析

Analysis on the seismic behavior prefabricated continuous beam bridge

支座是桥梁抗震设计的薄弱环节,文章对装配式连续梁桥抗震性能进行分析,以某连续梁桥为计算实例印证了大震条件下考虑桥梁的支座损伤,即支座作为保险丝式单元优先破坏,可以比较有效地控制梁体位移和墩底的地震反应。

The bearing is the weak point in the seismic design of the bridge. This paper analyzes the seismic behavior prefabricatedcontinuous beam bridge. A calculation example of a continuous beam bridge confirms that the bearing damage of the bridge is consideredunder the condition of large earthquake. That is the bearing as a fuse unit preferentially destroys the displacement of the beam body andthe pier Earthquake response at the end.
