Abstract

Aseismic hybrid control for high-rise buildings Y.P. Wang Department of Civil Engineering, Chung-Hua Polytechnic Institute, Hsin-Chu, Taiwan 30067, ABSTRACT Presented in the paper is a hybrid control system, referred to as the active isolation system, consisting of rubber bearings as base isolators and a hydraulic actuator to monitor the base motion of the isolated structure. A predictive control strategy is considered for control design of the active system. This algorithm is developed specifically for relative response reduction of base-isolated structures subjected to seismic excitation. Effectiveness and adaptability of the proposed system is verified through numerical examples. Influences of the design parameters and time delay on the control efficacy as well as the stability issue are discussed. Moreover, its performance is compared with that of a hysteretically damped base isolation system. Superiority of incorporating active devices over passive ones is clearly demo
