| 摘 要： | 采用船撞动力时程最大值、峰值范围内的局部平均值及全局平均值,作为船撞等效静力荷载对斜拉桥进行船撞静力分析,将结构静力响应与船撞动力响应进行对比分析。结果表明:斜拉桥结构位移响应、内力响应差别较大。建议针对存在船撞问题的斜拉桥,在设计时船撞分析尽量采用动力分析方法,以便得到更为真实的结构内力和位移响应。

| Abstract: | The response of cable-stayed bridge under vessel collision load by dynamic and static analysis was analyzed with the maximum and the local average and the global average of the dynamic time history of ship impact as the equivalent static load.After comparison of the results it could be obtained that the response of cable-stayed bridge was different when different methods were applied.It was suggested that the cable-stayed bridge crossing the navigable river should be designed by dynamic analysis under vesse... |
