摘要：
Nowadays, damage detection of bridge structure is a hot topic in academia and engineering. Based on the advantages of curvature mode sensitivity to structural damage, and the characteristics of perturbation theory high precision to identify, a structural damage detection method using modal curvature difference perturbation theory is proposed. The finite element model of a simply supported beam structure is established by ANSYS. Taking the relative curvature difference as damage index for damage detection, damage location analysis of structure is calculated at different damage degree, under the conditions of single damaged and multiple damaged of structure. Based on the perturbation theory, the damage location and degree are detected, and the numerical simulation method is used to verify them. The results show that the structural damage detection technique using modal curvature difference perturbation theory not only has high recognition precision, but also has important reference value for damage detection of bridge structure.
