摘要
采用实体有限元软件Midas FEA建立了全桥模型,从不同加载位置的车辆荷载、自重、二期均布荷载等方面,分析了大跨径预应力混凝土连续刚构桥箱梁的剪力滞效应,总结了其分布规律,以供类似桥梁设计参考。
The paper adopts the solid finite element,Midas FEA,to establish the whole bridge model,analyzes the shearing force lag effect of the large-span continuous rigid box girder from the vehicle loading capacity of various loading positions,gravity,and second-phase uniform distributed load,and sums its distribution law,so as to provide some reference for similar bridges.
