Location Preliminary Research of Structure Based on Modal Stain Energy Method
Abstract:In this paper, adopting the method based on modal strain energy to locate the probable damage positions of structure. It shows that we reach the target of narrowing the diagnose area from the numerical instance of three-dimensional space rigid frame, which has significant meaning for locating the damage positions of large-scale structure。
Keywords: space rigid frame modal strain energy damage location
