| Abstract: | In this paper, the vibration based structural damage detection of long span bridges is described as four stages. The vibration measurements and FEM model updating for damage detection are introduced. Some damage detection methods, such as the damage index method,the inverse analysis method, the pattern identification method, and the abnormity detection method, are discussed.Finally, some problems to be solved in structural damage detection of long span bridges are pointed out in the paper. |
