Abstract:

This paper presents an optimized fuzzy controller to adjust the damping of semi-active tuned mass damper used to decrease the vibration of building structures due to the earthquake excitations. The fuzzy controller is designed to apply the appropriate voltage of semi-active magneto-rheological (MR) damperworking as the tuned mass damper actuator. The fuzzy rules is planned based on the expert operator view of the physical behavior of the system. In this study, fuzzy controller is optimized by CSS algorithm to enhance the performance of the fuzzy controller in reducing the responses of the structure in seismicinducedvibrations. The optimized fuzzy controller is employed to modify the damping of a semi-active tuned mass damper attached on the top floor of a ten story building structure. The results of the proposed fuzzy controller are compared with those of the non-optimized fuzzy controller and passive tuned mass damper in two El-Centro and Tabas earthquake excitations. The outcomes demonstrate a good performance of the optimized fuzzy controller in reducing the responses of the structure
