摘要
介绍摩擦摆式减隔震支座在桥梁抗震设计中的应用,并结合"跨511路大桥"项目工程中(30+40+30)m连续梁桥,着重介绍了摩擦摆式支座的参数选取及隔震方案设计。根据采用普通支座和摩擦摆式支座两种方案的地震反应对比分析,论证了摩擦摆式支座在桥梁减隔震设计中的效果,并对该类支座在应用中存在的问题作了初步探讨,以供今后类似工程抗震设计参考。
Combined with the （30 ＋ 40 ＋ 30）m continuous girder bridge in ＂cross 511 Road Bridge＂ project engineering, this paper introduces the application of friction pendulum isolation bearing in bridge seismic design, focusing on the parameters selection and seismic isolation design scheme about friction pendulum bearings. Through comparative analysis of the seismic response of ordinary bearings and the friction pendulum bearings, this paper demonstrates the effects of friction pendulum bearings in bridge seismic isolation and the potential problems during the application, which can provide references for similar projects in the future.
