摩擦摆式抗震支座在现浇连续梁中的应用

The application of friction pendulum seismic isolation bearing in cast-in-place continuous beam

以一座四跨连续梁桥为研究对象,结合土木工程通用有限元分析软件Midas分析地震力作用下桥梁使用普通盆式支座和摩擦摆支座对桥梁下部结构受力性能的影响,分析结果表明在地震力作用下,装有FPB隔震支座桥梁比非隔震支座桥梁具有良好的隔震效果。

Taking a 4-span continuous beam bridge as the research object, combining with civil engineering general finite element analysis soft- ware Midas to analysis the bridge stress performance influence using ordinary pot bearings and friction pendulum bearing to bridge lower part structure under seismic force, the analysis results showed that under seismic force, the bridge equipped with FPB seismic isolation bearings had good seismic isolation effect than general isolation bearings.
