Seismic performance of existing brittle R/C buildings is discussed based on energy balanced response and thc relation of Seismic Structural Capacity Index (Is-index) and the energy input is discussed in this paper. Based on the discussions above, the seismic performance of existing R/C buildings with hysteresis dampers are evaluated based on energy response. The nonlinear time-history analysis results shows the proposed equations can be satisfactorily estimated the seismic performance of existing R/C buildings with hysteresis dampers.
