Abstract:
Authors introduced a new semiactive control system, active variable stiffness·damping(AVS·D)system, whose composition and work principle were described. The AVS·D system was capable of amplifying the interstory drift and velocity and made dampers dissipate more energy. In this study, the control law of the AVS·D system was derived based on an instantaneous performing index. To optimally utilize the AVS·D control devices and economically improve the control performance, genetic algorithm(GA)was used to design the multiple device location. Numerical simulation indicates that the AVS·D system is a new semiactive control system with high performance and the proposed instantaneous control law of the AVS·D system is quite effective. The proposed procedure of optimizing the placement of AVS·D devices is high efficient, which can make the most advantage of AVS·D system.
