摘要
利用大型通用软件ANSYS对长江下游某大跨度钢桁架拱桥做几何和材料双重非线性、几何非线性、线弹性等三种情况下的极限承载力对比分析,从而得出非线性因素对钢桁架拱桥极限承载力的影响,以及符合结构实际的极限承载力。
In this paper, using ANSYS to analysis the Ultimate Load Capacity a long - span steel truss arch bridge in three cases,such as double nonlinear of geometry and materials, geometry nonlinear, flexibility. Then through comparative analysis, work out the influence of nonlinear factors on the ultimate load capacity of steel truss arch bridge.
