| Abstract: | A method for damage positioning is developed on the basis of testing the variation ratio of squared frequency.A simply supported beam is simulated.Results show that the damage parts of structure are identified by the method.The method is invalid in the symmetric structure. |

| Keywords: | fault diagnosis variation ratio of squared frequency simply supported beam |
