斜拉桥多模态抖振分析

Multimode Buffeting Analysis of Cable-stayed Bridge

在已有桥梁抖振频域分析理论基础上 ,着重考虑相同运动方向的模态耦合 ,推出相应公式 ,并对南京长江二桥进行了实例分析。

On the basis of up?to?date buffeting theory of bridge in frequency domain, this paper stresses on the mode coupling of the same motion direction and presents numerical results with practical example to test the theory.
