谈城际高速连续梁桥铅芯橡胶支座减隔震

On lead rubber bearing seismic mitigation and absorption of inter-city express continuous beam bridge

结合城际高速连续梁桥的抗震设计现状,介绍了桥梁结构抗震设计传统方法的局限性,提出了铅芯橡胶支座减隔震设计措施,指出铅芯橡胶支座具有较高的延性和柔性,可起到良好的隔震效果。

According to the seismic design of some inter-city express continuous beam bridge, the paper introduces the limitation of the traditionalmethods for the seismic design of the bridge structures, points out the design methods for the seismic mitigation and absorption of the lead rubberbearing, and indicates it has better ductility and flexibility, so it has better seismic effect.
