Research on Isolation Properties of Friction Pendulum Bearing for High-speed Railway Bridges

  • 摘要: 以我国高速铁路桥梁为例,建立合理的摩擦摆隔震桥梁力学模型,并通过数值模拟,对摩擦摆支座在高速铁路桥梁上的隔震效果进行研究。研究结果表明:建立隔震桥梁双自由度力学模型,能够较为准确地计算出隔震桥梁的地震响应;选用不同地震波,摩擦摆摩擦因数对高铁主梁最大位移影响规律不同;通过在桥墩与主梁间设置摩擦摆隔震装置,高铁桥梁主梁加速度、墩底剪力、墩顶位移隔震率分别可以达到40%、35%、50%;墩底剪力、主梁位移响应幅值随着桥墩高度增加有很大增加。
