Abstract：In order not to increase the weight of the structure, and make the TMD principle well applied to the structural seismic response control of tall building .This paper presents a TMD system. In this system, dead loads and live loads of ribbed floor are converted into the quality of substructure and lateral stiffness and damping of rubber isolation pad set in the main beam (including beam) and ribbed slab replace the spring and damper of substructure. Based on the study of rise building with TMD , vibration differential equations and computer programs are established for elastic-plastic time history analysis and the rationality and feasibility of the system is discussed. Research on design method of TMD based on fixed point theory. Calculate the seismic responses of original structure and energy dissipation structure under a variety of earthquake actions and compare the energy distribution. By considering the effect of the TMD location on energy dissipation structure seismic response and analyzing the feasibility and scheme of the TMD used in practical engineering, finally a simple and effective design method of TMD is presented- the theory of fixed point correction method. Based on this method , case models are used to calculate and analyze. It is proved that structure using this method has better effect of energy dissipation and the theory of fixed point correction method is reasonable and reliable .
