高阻尼橡胶支座对连续梁桥抗震性能的影响

The Influence of High Damping Rubber Bearing on Seismic Performance of Continuous Beam Bridge

抗震设计是连续梁桥设计的重要环节,在介绍高阻尼橡胶支座的基础上,研究其对连续梁桥抗震性能的影响。研究发现:高阻尼橡胶支座可以改变连续梁桥的动力特性,可以大幅减小连续梁桥的内力和位移响应,是一种有效的减隔震装置。

Seismic design was an important link in the design of continuous beam bridges. Based on the introduction of high damping rubber bearing, the paper discussed the influence on seismic performance of continuous beam bridge.h was proved that high damping rubber bearing could change the dynamic characteristic of continuous beam bridge, dramatically reduce its internal force and displacement response and which was an effective seismic-isolation device.
