The concept of connecting two adjacent buildings has been effectively used to mitigate the structural responses of such buildings due to strong ground motions. Lots of analytical and experimental studies have shown the efficiency of this conventional strategy for dissimilar coupled buildings. However, it is absolutely inefficient for the similar connected buildings. The authors, in their previous works, have provided a new Hybrid Coupled Building Control method (HCBC method) which is applicable to all adjacent buildings. This control strategy reduces the structural responses, and thus reduces the internal forces, of the connected buildings more efficiently than the conventional Coupled Building Control method. In order to apply this strategy, one of the buildings is equipped with a base isolation system, and an active actuator link connects the upper floor of the shorter building to its corresponding floor of the other building. In this paper, the HCBC method is developed for the similar coupled buildings. Herein, this structural control method is applied to two similar connected moment-resisting frame buildings. The best performance of the system is obtained, by designing the control system, so that the two connected buildings stay within their elastic range due to the ground motions. The performances of the HCBC models using active and passive strategies are also compared in details.
