ASEISMIC HYBRID CONTROL SYSTEMS FOR BUILDING STRUCTURES

This paper studies the feasibility of the hybrid control concept, and proposes two types of hybrid control systems for seismic excited tall buildings. The hybrid systems consist of a base-isolation system such as elastomeric bearings, connected to either passive or active mass dampers. The performance of these two hybrid cotrol systems is evaluated and compared with that of an active control system for a 20-story building subjected to a strong earthquake. It is shown that the proposed systems are very effective in reducing the response of tall buildings under strong earthquake excitations, and that they may be more effective and advantageous than the application of an active control system alone.
