| Abstract: | Applying the wavelet packets decomposition techniques,sensitive parameters for damage identification based on the comprehensive energy curvature difference were constructed,and the structural damage localization and quantification were investigated the numerical simulation of some damage cases for a 3-dimentional frame structure was carried out.Experimental results indicate that the damage identification method presented has good performance for structural damage identification. |
