摘要
以一座大跨径悬索桥的桥塔方案为研究对象,运用大型有限元软件ANSYS研究了该钢结构桥塔的极限承载力,计算结果表明,只有综合考虑结构的几何和材料非线性才能准确的评估出结构的极限承载力。
In this paper, taking a long span suspension bridge pylon project as the object, the ultimate bearing capacity was studied using FE program（ANSYS）. The calculated result shows, only both considering geometrical and material nonlinear, the ultimate beating capacity of the structure should be estimated precise.
