Nonlinearity of isolation system as well as that of superstructure is considered. Selection and scaling of ground motions have more pronounced effects on superstructure response. Mean base shear forces and floor accelerations are less severely affected. Curvature ductilities show largest dispersions. Lengthening of fundamental period is more efficient than increasing effective damping.
