This paper presents the performance based parameter analysis of two base isolated buildings with linked non-linear viscous damper under severe random earthquake excitation. From two viewpoints of preservation of seismic safety and improvement of structural comfort, the optimum parameter on the non-linear viscous damper is determined in such a way that the responses of two base isolated structural systems with linked damper agree with the performance-based responses of the base isolated system without damper. The optimality of the parameter is discussed for the yield strength and initial stiffness of the isolation interface, some random earthquake excitation models and the fundamental period of two base isolated buildings or upper structures.
