| 摘 要： | 采用ANSYS软件建立某双塔斜拉桥的有限元模型,计算全桥不同位置斜拉索的突然破断对剩余结构造成的动力响应,通过对比,获取造成最大动力响应的斜拉索位置。同时,对破断拉索位置进行参数分析,找出断索分析中的关键拉索,所得结论期望用于工程设计中的断索工况校核。

| Abstract: | In the paper,the finite element model has been developed for a double pylon cable-stayed bridge by using ANSYS.The dynamic responses of residual structure induced by sudden cable breakage of different stayed cable have been calculated.By comparison,the cable location that causes largest response has been obtained.At the same time,the parameter analysis of broken cable position has been performed to find the key cables.The results could be used for the condition calculation of cable breakage in engineering design. |
