摘要
采用有限元软件ANSYS建立矮塔斜拉桥跨中箱梁局部有限元模型,结合总体计算情况,对结构在不同加载工况下的薄壁箱梁的剪力滞效应进行计算分析,分析了箱梁受力,得到了其剪力滞分布状况,供设计人员参考。
By using the software ANSYS, the paper establishes a local FEM model of the box girder of an extradossed bridge. With the overall calculation, the paper does a computational analysis of the shear lag effect of the thin-walled box girder under different loading conditions. It also analyzes the stress condition of the box girder and summarizes the distribution of its shear lag distribution, with a view to provide reference for de- signer.
