Viscous damper is effective device to control earthquake response of buildings passively. But because of phase differences between restoring force of structures and damping force of viscous dampers, that is time lag between maximum restoring force and maximum damping force, it is difficult to design on the basis of resisting force of buildings against inertia force of earthquakes. In this study, energy dissipating behaviors of RC structures with viscous dampers subjected to earthquakes, are investigated. By considering input and dissipated energy during a half cycle of response, earthquake response of buildings is recognized as input and dissipating process of energy, and response level of buildings will depend on properties to dissipate input energy of earthquakes. By these results, the concept and several examples of a procedure to predict inelastic response displacement of RC buildings by corresponding earthquake input energy to dissipated hysteretic and damping energy, are shown.
