【Abstract】 A method to select the optimum parameters of tuned mass dampers (TMD) is presented. The criterion used to find the optimum parameters is to minimize the maximum value of the amplitude of normalized steady_state frequency response of the main structure by numerical searching procedure. Numerical solutions for the optimum parameters are given in tabular form. 60 ground excitation records are selected to examine the control effect of TMD to the structures with different periods and damping ratios via statistical analysis.更多还原
