| Abstract: | A new damage identification index is expatiated. The checking computations of the index stability are done and the percentage curves of the index varied with the damage degree are plotted. The result of numerical simulation is shown that the inddex is sensitive to small damage and it can be used to judge and evaluate the structure damage. It has some potential application |
