摘要
采用非线性有限元法(U.L列式法)对钢管混凝土拱桥在静风荷载作用下的几何非线性行为进行了计算与分析,得出在风荷载作用下钢管混凝土的几何非线性因素不可忽略的结论。
The nonlinear finite element method （ U. T column - wise method） was used to compute and analyze the geometric non - linear behavior of the concrete - filled steel - tube arch bridge forced by the wind load. Result showed that the geometric non - linear factor must not be neglected when a concrete - filled steel - tube arch bridge is forced by the wind load.
