摘要: 提出了一种采用铅芯橡胶支座进行大跨度斜拉桥减震分析方法;分别建立了大跨度斜拉桥、铅芯橡胶支座的空间有限元分析模型,采用时程分析方法计算了桥梁地震响应;用正交设计法对铅芯橡胶支座进行了参数优化。 研究表明:经过优化设计的铅芯橡胶支座能有效的减小斜拉桥在地震下响应。

关键词: 大跨度斜拉桥, 铅芯橡胶支座, 正交设计, 减震

Abstract: Reducing vibration by leadrubber bearings was proposed in longspan cablestayed bridge.Spatial finiteelement models of a long spancable stayed bridge and LRB swere established respectively. Seismic responses of the bridge were calculated through time history analysis; parameter optimum of LRBs was carried out by orthogonal design.The results indicated that LRBs with optimization design could effectively reduce seismic response of the cablestayed bridge.

Key words: Long span cable stayed bridge, lead rubber bearings(LRBs) , orthogonal design, seismic reduction
