As a fundamental study to develop a force-displacement-based seismic design of RC piers, the acceleration-displacement response spectrum (ADRS) of SDOF systems with elastic-plastic bilinear restoring force characteristics is obtained by inelastic response analysis, provided that the value of modified Park-Ang damage index D of a SDOF system equals the required value Dr=0.4 that almost correspond to the repairable limit of the system. The regression equation of ADRS is derived and applied to a force-displacement-based seismic design of a single-column RC pier. The design results by the proposed method are compared with the ones by the ductility design method of Japanese Specifications.
