The study of the steady-state vibration of a system under sinusoidal excitation can provide important insights into the more general dynamic response structures. The response of seismically-isolated structures with viscously-damped isolation system was previously studied by the authors. This paper presents the non-linear steady-state vibration of seismically-isolated structures with hysteretically-damping isolation system. The solution method for the steady-state vibration of the non-linear system is based on the work of Tajimi, and expanded to seismically-isolated structures. The non-linear superstructure behavior is significantly different from that of fixed-base structure. Consequently, the important aspects for isolated structure design is highlighted.
