摘要

以鲁疃西路跨温榆河大桥为工程背景,研究了大跨度梁拱组合桥的减、隔震设计方法。建立全桥有限元模型,进行了自振特性分析。给出了摩擦摆支座隔震设计的方法及步骤,并进行了摩擦摆支座隔震及阻尼器减震的非线性时程反应分析。结果表明,摩擦摆支座隔震优于阻尼器减震,能显著地减小墩底弯矩与拱顶的变形响应。
Isolation design method of long span girder-arch bridge is studied based on the Wen-yu river bridge located in Lu Tuan West Road in Beijing.The finite element model is established and the natural vibration characteristics is performed.Isolation design methods and procedures for the friction pendulum bearings are given in detail.The nonlinear time-history response analysis is respectively performed for the friction pendulum bearings and damper.The results show that the friction pendulum bearings can significantly reduce the deformation of the vault and the moment of bottom of pier,better than the damper.
