Abstract

Abstract: This study proposed a new semiactive control device for building control. Semiactive tuned mass damper (STMD) combine a tradition tuned mass damper (TMD) and a semiactive damper. The property of semiactive damper can be adjusted online to produce the desired control force. In the present year, many types of semiactive dampers are proposed. In this study, the variable damping device and MR damper are used to illustrate the control effect of STMD. In addition, the control effect of the TMD and active tuned mass damper are also compared. The numerical simulation results show that the STMD can greatly improve the control efficiency of TMD.
