Also, the extent of enhancement for the damping ratio of a civil structure with the EDS and the aseismic capability of the structure have been studied. In addition, factors related to the effectiveness of vibration reductions have been studied numerically and experimentally. It is expected that a damping system which is suitable for use on buildings can be developed. Topics of study are as follows: (1)To investigate theoretically and numerically the feasibility and the effectiveness of the EDS on the improvement of the aseismic capability of the buildings. (2)To verify the accuracy of results and the related limitations of the theoretical analysis and numerical simulation using the shaking table experiments. (3)To develop the methods of analysis and procedures for seismic design and retrofitting of buildings with the EDS, especially for the RC building. (4)To perform the aseismic retrofitting analysis and design of a real RC building damaged in earthquake for demonstration. The results of the present study are as follows: (1)The damping ratio of a building structure can be largely increased and the seismic responses of the building can be reduced by using the EDS. Along this line, the aseismic capability of the building can be improved extensively. (2)The seismic responses of a building with the EDS can be analyzed by using the response spectrum method to obtain the conservative results for design or retrofitting of buildings if the damping coefficients of the device systems have been adjusted following the rule proposed in the present study. (3)The pseudo relative velocity (SV ) used to estimate the maximum damping forces developed in the fluid dampers of the EDS during earthquakes has been proposed which can be obtained by using the method of response spectrum analysis. (4)The method of analysis and the design procedures for establishing and seismic retrofitting of the RC building with the EDS have been proposed. In addition, the seismic retrofitting of a real 15-story RC building has been analyzed and designed for illustration.
