Coupled Building Control (CBC) has been effectively used to help mitigate the extended responses of the adjacent tall buildings due to strong ground excitations. Extensive analytical studies and experimental tests have shown this control strategy works well for "dissimilar" coupled buildings, but it's completely inefficient for the "similar" buildings. Recently, an innovative scheme for structural control, named the Hybrid Coupled Building Control (HCBC), has been presented by the authors, which improves and develops the CBC strategy. HCBC is applicable to all adjacent buildings; in order to apply the HCBC strategy, one of the adjacent buildings will be equipped with a base isolation system, and an active actuator link will connect the two buildings at a floor level. The primary buildings may be similar or dissimilar but, as a desired case, the "similar" buildings will be concerned here. In the previous works, it's shown that HCBC strategy efficiently decreases the maximum drifts and accelerations of the buildings. This paper investigates the effects of connector location on the performance of HCBC strategy. Analytical results for different configurations are presented in details, and the best choice is introduced.
