In Japan, long-period earthquakes or extreme seismic events that exceed the assumed level of structural design codes are concerned to occur in the future. Such concern will argue the requirement for response displacement control of structures in terms of dynamic design. In such circumstances, the authors advocate a new idea on dynamic structural design; "the displacement control design". The conventional viscous dampers such as oil dampers are not necessarily optimal for displacement control design since they exert damping force corresponding not to the displacement but to the velocity. Complex stiffness is useful to model a displacement dependent damper as its response amplitude of damper force does not vary with respect to the frequency. The effectiveness of the displacement dependent damper using complex stiffness is discussed in this paper.
