This study proposed immediate estimation method for structural integrity using acceleration responses after earthquake. Generally, structural damage detection searching for changes in the natural frequencies by acceleration data. However structure’s natural frequency is changed without damage because of various environmental factors. So that reason, we suggested structural safety estimation procedure using various indicators from analyzing acceleration data. This method is not exactly evaluated structural damage, but using this method is simple to make a decision.
