Abstract:
To study structural damage and damage detection index, a structural damage method with strain frequency response function(SFRF)as damage detection parameter was presented. The structural damage index SFRF curvature ratio was presented. Based on the method, an example was analyzed under some conditions, such as simple-supported plane and multi-damage. The results show that the SFRF curvature ratio is sensitive to damage than the methods, such as modal shape, modal strain and FRF. The presented method can be applied to location of structural damages as well as identification of damage severity.
