摘要
通过有限元建模,对某特大跨径双塔双索面斜拉桥在移动载荷激励、风致激励和地震激励下进行了空间动力分析,并给出其振动模态与激励耦合位移,建模过程与分析结果可供相关设计参考。
According to limit unit building mould, it analyzes the special dynamic force of a specially big span double tower double rope surface diagonal cable bridge in moving load drive, wind-cause drive and earthquake drive, and gives displacement of vibrating mode and drive coupling, the process of building mould and analyzing result can provide reference for correlated design.
