摘要
施工阶段斜拉桥的颤振稳定性已成为一个倍受关注的重要工程问题。运用多模态颤振的有限元分析方法 ,进行了施工阶段的颤振稳定性分析 ,并探讨了施工阶段斜拉桥结构动力特性和颤振稳定性的变化规律。
Flutter stability is a major concern problem for cable stayed bridges in erection. Using the method of finite element analysis based multi mode flutter, the flutter stability of the Jingsha Bridge over the Yangtze River during erection is analyzed. The variations of structural dynamic characteristics and flutter stability are finally illustrated.
