Abstract

Coupling adjacent buildings with supplemental damping devices is a developing method of mitigating structural responses due to wind and seismic excitations. The concept is to allow structures, vibrating at different frequencies, to exert control forces upon one another to reduce the overall responses of the system. Selecting a coupled building configuration that provides for the greatest response reduction is important in determining which building clusters are candidates for coupling. This paper studies the effect of the height, mass and stiffness of two actively coupled high-rise buildings and the location of a single coupling link. Connecting the buildings at the top of the shorter building provides the greatest response reduction. A particular coupled building system is used to shown that a smart damping strategy can achieve nearly the same performance as the active control strategy, giving 99% of the response reduction achievable in the active control.
