| 摘 要： | 用能量法对变截面薄壁空心墩进行几何非线性分析,通过考虑和不考虑几何非线性两种情况进行对比计算,计算结果表明几何非线性对变截面空心墩的影响随着墩高的增加而增大,但其增大的幅度不是很大,当墩的长细比较大时,几何非线性的影响不能忽略。

| Abstract: | The paper analyzes the geometric nonlinear effect of the nonuniform thin-walled hollow pier by the energy method.Considering the geometric nonlinear effect and not,the contrast and computa- tion result shows that the higher the pier,the more evident the geometric nonlinear effect on nonuni- form thin-walled hollow pier,but the increase is not great.When the slenderness ratio of the pier is great,the geometric nonlinear effect could not be ignored. |
