Abstract

Abstract: Tall piers, with incipient defect, are regarded as investigative object.With the considerations of the effects of geometrical and material non-linearity, the tall piers are analyzed by non-linear stability analysis through / ANSYS0 . And the obtained results are compared to those by linear analysis.

Key words: tall pier, defect, non- linearity, FEA, stability

摘要： 笔者以具有初始缺陷的高桥墩为研究对象,在考虑几何非线性和材料非线性的基础上,利用ANSYS进行非线性稳定分析,并将其结果与线性分析结果进行比较.

关键词: 高桥墩, 缺陷, 非线性, 有限元, 稳定
