According to the being three-dimensional, interweaving responses of the structure with each other, cohesiveness of behavior of superstructure and base level and computing the nonlinear force of base isolation systems, this building is very complex. Under these circumstances, we used extended sliding mode theory to applying the benchmark building. Also, the actuators are located only at the base level and in the two main directions. The results indicate that the proposed control system improved the building responses.
