摘要
针对安徽省涡河三桥双索面斜拉桥主塔设计这一工程实例,基于弹性稳定理论研究其两类稳定性问题,采用ANSYS软件建立该桥钢结构主塔的等效实体有限元模型,分别进行屈曲模态分析和非线性屈曲分析。分析结果表明:自重条件下主塔结构整体稳定性较好,可满足工程需要。
Stability analysis based on elastic stability theory of main tower of a cable-stayed bridge in Anhui province is studied,which is designed using water droplets shape.The finite element program ANSYS was used to establish the equivalent model and investigate the stability of the tower.The results show that the main tower structure overall stability is well,which meet the demands of engineering practice.
