Predictive Control for Earthquake Response Mitigation of Building With Semi-Active Fluid Dampers

Abstract

ln this paper a predictive control strategy in conjunction with sem i-active control algorithms are proposed for damping control of base isolation systems employing semi-active fluid dampers when subjected to earthquakes. Twenty artificial accelerograms for the Portuguese territory were considered in the numerical simulations of the base isolation system representative model. The results of a parametric study give some hints for controller design in this type of problems. It will be shown that a well tuned controller could outperform the original structure and the structural system with a passive device (optimized) in terms of performance: relative displacement and absolute acceleration reductions.
