The contents of this study are (1) to understand the relationship between the maximum relative displacement of floors by response spectrum method and the maximum relative velocity of floors by time history analysis. Along this line such that the maximum damping forces of the fluid dampers can be estimated. (2) to understand the stress states of the connecting sections between the efficiency-enhanced damping device and the structural members. and (3) to develop the method of analysis and design procedures for seismic retrofitting of the RC buildings with the efficiency-enhanced damping device system. In addition, the seismic retrofitting of a 20-story RC building is analysis for demonstration. The contribution of the present study are (1) the pseudo velocity (SV) which can be used to estimate the maximum damping forces developed in the fluid dampers during earthquakes with the response spectrum analysis being defined and (2) the method of analysis and the design procedures for seismic retrofitting of the RC buildings with the efficiency-enhanced damping device being proposed.
