竖向地震动对摩擦摆支座隔震桥梁地震反应的影响

Effect of Vertical Ground Motion on Seismic Response of an Isolated Bridge with FPS

以某高墩大跨简支钢桁梁桥为实际工程背景,以摩擦摆支座的滑动曲面半径及滑动摩擦系数为主要参数,系统研究了竖向地震动强度对摩擦摆隔震桥梁地震反应的影响,并探讨了摩擦摆支座在高墩大跨简支钢桁梁桥中的减震效果.

Taking some tall piers and long span simply-supported steel truss girders as practical engineering background,and based on main parameters of the sliding curved surface radius and the sliding friction coefficient,the effect of vertical ground motion on seismic response of the isolated bridge with FPS is systematically researched and the seismic response reduction of tall pier and long span simply-supported steel truss girders with FPS is investigated.
