| Abstract: | FEM analysis of bridge damage diagnosis based on curvature mode theory to be studied in this paper.And it is proved that curvature mode is a sensitive index in damage diagnosis for whole bridge structure or for part of it. Some useful conclusions for girder bridge are drawn in this paper and it can serve as references for real bridge damage diagnosis. |
