斜拉桥材料非线性静力分析
Material Nonlinear Static Analysis of a Cable-stayed Bridge
使用截面分层法计算斜拉桥混凝土主梁在不同轴力下的弯矩-曲率曲线。并使用有限元杆系模型的塑性铰方法对某主跨为140米的斜拉桥进行材料非线性分析，并将非线性分析与线性分析进行对比。发现材料非线性对个别拉索索力影响达到84%. 建议进行斜拉桥设计时计入材料非线性影响。
By dividing the cross-section into stratum, this paper calculated the Moment-Curvature graphics of the concrete girder which is under different axis force. In the paper, a bar-system FEM model of a 140m span cable-stayed bridge was built, and material nonlinear analysis was undertaken with plastic-hinge method being used.It was found that the effect of material nonlinearity reached 84%. Material nonlinearity should be calculated in the engineering of cable-stayed bridge.
