In recent years, response control structures have been widely applied for the seismic performance based design of new buildings and retrofit of existing buildings to achieve high seismic performance. And the prediction method based on energy balance has been presented for them, however it is limited for the case the response of main structure remains in elastic range. In this paper, the prediction method based on energy balance is extended for the case of the main structures respond beyond elastic range. In this method, the maximum response is obtained from the energy balance at the time the maximum response occurs and the cumulative energy response is obtained from that of whole energy during earthquake. The validity of the proposed method is examined by nonlinear time-history analysis.
