摘要

用有限元软件Midas对某斜拉桥的动力特性和地震响应进行了空间非线性时程反应分析,考虑桩-土相互作用,对支座参数进行优化,通过分析对比桥梁在阻尼、非阻尼两种状态下的地震反应,验证了阻尼支座的隔震效果。
To analyze the dynamic characteristic and seismic responses of a cable-safety stayed bridge with considering the interaction between the pile and the soil as well as the effect of the pile group,the isolated effect on the cable-stayed bridge is analysed with Midas.The damping constant is optimized. Compared with no-isolated and isolated structure,the isolation effect of lead rubber bearing on the total bridge structure with the characteristics of the input seismic ground motion is also confirmed.
