Abstract
In this paper, a control strategy to reduce the vibrational response of adjacent
buildings under seismic excitation is presented. The proposed strategy combines passive
linking elements with an active decentralized H-infinity control system. The overall active-passive
control system admits decentralized design and operation, and achieves an excellent vibrational
reduction when the active control system works; in case of a full or partial failure of the
active control system, a remarkable reduction in the vibrational response is guaranteed by
the passive linking elements. For adjacent buildings that require different levels of seismic
protection, the implementation of an active H-infinity control system in just one of the buildings is also
considered. The main ideas are presented by means of a simplified two-building model. Numerical
simulations have been carried out to assess the performance of the proposed methodology with
promising results
