| 摘 要： | 针对某大跨度悬索桥高达195.3 m的主塔,采用通用有限元软件ANSYS10.0建立三维有限元计算模型,分析了几何非线性和材料非线性对主塔稳定性的影响,计算结果表明,几何非线性和材料缺陷对主塔的稳定性影响明显,在设计计算中要考虑受风荷载后的非线性稳定性。

| Abstract: | According to the situation for the main tower of some large-span suspension bridge with the height of 195.3 m,the paper adopts the common finite element software ANSYS10.0,to establish the three-dimension calculation model,analyzes the influence of the geometric nonlinearity and material nonlinearity on the stability of the main tower,and proves by the calculation results that the influence of the geometric nonlinearity and materials defection on the stability of the main tower is obvious,so the non-linear stability of the wind load in the design calculation. |
