This paper develops an analytical approach to the optimality of hysteretic-type passive damper on the basis of seismic random earthquake response analysis. Numerical calculations are carried out for multi-degree-of-freedom elasto-plastic systems, and the optimality of parameters of hysteretic-type damper are examined in terms of structural seismic safety and improvement of structural amenity. The parameters discussed are the stiffness ratio between bare frame and hysteretic-type passive damper and the yield displacement level of the damper. The control efficiency of structural systems with the optimum hysteretic-type damper and the usefulness of the analytical approach under seismic random earthquake excitation are demonstrated through the simulation analysis using recorded earthquake accelerograms of El Centro (1940) and Kobe (1995) earthquake.
