【Abstract】 In this paper the reduction effects on the seismic response of tall building are investigated by applying the suspended mass pendulums and the approach of reducing multi modal responses of tall building using this device is presented. The mechanical models and equations of motion for tall buildings with the different suspended way pendulums are given and then the effects of different suspension way of pendulums and ratio of the pendulum and structure masss on the structural seismic responses are studied by employing the numerical analysis. Finally some conclusions with practical engineering significance are gotten.更多还原
