Researchers have developed various control devices to make the control strategy very effective for seismic response control. Out of various control system, semi-active control devices have emerged as very attractive systems, for their obvious advantages of reliability and versatility, over last one decade. It has been found that pounding between adjacent building have caused significant damage in past major earthquakes, therefore, to address this problem a scheme of coupled building control has been devised by the researchers. Under this the adjoining floors of the two adjacent buildings are rigidly connected through inline dampers, such as a system has dual advantage of pounding avoidance and response control for both the buildings. In the present study the effectiveness of one of the most promising semi-active devices, namely, variable friction (VF) damper is being investigated under coupled building control scheme. The efficacy of the proposed strategy is investigated taking numerical example of two adjacent buildings of twenty and ten stories respectively. Further, the influence of VF damper gain multiplier on the performance of the control strategy is also examined. The results have showed that the effectiveness of VF damper for seismic response control under coupled building control. It has been noted that the performance of the control scheme is influence by the VF damper gain multiplier parameter and there is an optimum value of the same.
