大跨径连续刚构桥箱梁剪力滞效应分析

摘要

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.%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。
