ON THE FLUTTER INSTABILITY OF A SUSPENSION BRIDGE USING THE FINITE ELEMENT METHOD
The study of aeroelastic instability is fundamental for the feasibility of a large span suspension bridge. The determination of the flutter wind velocity is generally determined by a two-degrees-of-freedom model. In this paper an analytical model is developed to predict the flutter behavior of a suspension bridge, with a multi-degrees-of-freedom system. A finite element technique is employed. The numerical difficulties related to the solution of the problem are discussed. A suitable method is developed to increase the numerical stability of the solution. As an example, the results of the method are applied to the Messina crossing project.
