摘要
利用有限元软件MIDAS建立模型,针对三塔悬索桥结构的复杂性和结构特点,围绕结构不同的特征参数进行了反应谱分析,得出的结论为多塔悬索桥的抗震设计提供参考。
The model is established by MIDAS software. In allusion to the structure complexity and characteristic of three towers cable-rope bridge, surrounding different structure characteristic parameters, the response spectrum analysis are carried out. The conclusion can be used as reference for the anti-seismic design of multi-towers cable-rope bridge.
