Passive vibration control of multi buildings connected with hybrid magnetorheological damper

In this paper we propose a passive vibration control method for multiple high-rise buildings arranged in parallel. Using this method, it is possible to control vibrations of high-rise buildings against strong winds and large earthquakes. In this study, two model buildings are connected with hybrid MR (Magneto-Rheological) damper. The objective of this research is to control the first and second bending modes of each building using the proposed method. The control effect is evaluated by exciting the base of the structures by time response and measuring the frequency response of the structures. Both simulation and experimental results show that fairly good control performance has been achieved by this method.
