Abstract

An optimal design method for a hybrid control system is proposed in this study. Unlike conventional design approach, passive and active control systems are realized as a combined system and they are simultaneously optimized considering multi-hazard excitations. From the initial design stage, a state space equation is developed including the dynamic characteristics of the both systems and multiple loading conditions. A simultaneous optimization problem is formulated by introducing a preference model and the genetic algorithm is employed in order to find the optimal distribution and capacities of the control devices. An example design for a 30-story building with an active tuned mass damper and viscous damping devices is taken into account and numerical simulations are performed. The comparative results demonstrate the effectiveness and validity of the proposed method.
