| Abstract: | 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. |
