Discussion on the dynamic characteristics and optimum design of the structure-MTMD system under earthquake is made in the present paper. With resorting to numerical analysis, the research is carried out on the relationship among the design parameters of MTMD. The suggestion selecting the optimum parameters of MTMD is given. The design approaches for both the MTMD and structure-MTMD system under earthquake are proposed. Eventually, the numerical simulation for a 25-storey steel structure is conducted to demonstrate the application of the proposed method and effectiveness of MTMD in the mitigation of the seismic response of structures.
