| 摘 要： | 按等效线性化方法对一系列不同铅销含量的铅销橡胶支座进行了讨论,比较了其对桥梁的振动性能的影响,分析了产生影响的原因,并对一座安装铅销橡胶支座的钢筋混凝土连续箱梁桥进行了地震反应计算,对其抗震性能进行了对比分析,并与实测结果进行了比较,证明铅销橡胶减震支座的应用对桥梁的抗震性能有很大的改观。

Influence of lead rubber bearing on earthquake resisting behavior of bridges |
| |
| Abstract: | A series of lead rubber bearings with different quantity of lead was discussed with effective linearisation,the influence on the vibration behavior of bridges was compared,and the reasons were analyzed.The seismic response of a concrete box-beam bridge with lead rubber bearings was calculated,and the earthquake resisting behavior was analyzed.Compared with the test results on a constructed bridge,it was proved that the vibration behavior of the bridge was greatly changed with applying the lead rubber bearings. |
