摘要
以某高速铁路客运专线上采用摩擦摆式支座的32 m简支梁桥为研究对象,根据结构的特点,利用非线性时程反应分析方法对不同地震动输入条件下隔震支座的抗震、减震效果进行了分析,为铁路桥梁的抗震设计提供了参考。
Taking 32m simply supported beam bridge using friction pendulum bearing in a high-speed railway passenger dedicated line as the research object,according to the structure characteristics,using the nonlinear time-history analysis method analyzed the seismic of isolation bearing under different earthquake input conditions,the vibration reduction effect,provided reference for the seismic design of railway beam bridge.
