摘要
Abstract
The damages of a substructure were identificated by the proposed identification method.Numerical simulation examples indicate that the damage location and severity in structures,with single damage or multiple ones,can be detected efficiently by GMFCD through only a few of the lower order modal parameters.Compared to the aforementioned flexibility indicators,such as the change in flexibility,flexibility differential curvature method,the effectiveness and advantages of GMFCD are shown.关键词
