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.

Reducing vibration by lead-rubber bearings was proposed in long-span cable-stayed bridge.Spatial finite element models of a long-span cable-stayed bridge and LRBs were 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 r...
