摘要
几何非线性效应是影响大跨度斜拉桥结构计算的重要因素,通过分析各项几何非线性因素产生的原因,给出其基本理论和计算方法,应用有限元模型实现了考虑几何非线性影响的仿真计算,结合算例,定量分析各项因素对斜拉桥结构计算的影响。
The geometric nonlinear behavior of a cable-stayed bridge is studied in this paper, and the theory and method of analysis are put forward. A FEM model that considers geometric nonlinear behavior is established, in the calculation example, the effects of geometric nonlinear behavior on a quantity level are analyzed.
