Structural control devices are widely implemented in order to reduce the seismic response of buildings. These devices are typically categorized as hysteretic dampers and viscous dampers. If the structures employ only one of these dampers, the prediction of seismic response under strong motions is not difficult. However, it is desirable to predict the seismic response of buildings using both dampers simultaneously, because the use of these dampers to improve the seismic performance of buildings has increased in recent years. A prediction method called the energy balance-based method has been proposed in past studies to evaluate seismic performance. This sentence is confusing. I suggest the following: The existing method is able to predict the response of control structures with one type of damper. However, the existing method has not been able to predict the seismic response of buildings with multiple dampers.This paper describes a method that can handle these cases by rearranging the mathematical expression presented in past studies.
