| Abstract: | Based on Chinese wind load code and with resorting to both the pseudo excitation method and mode reduced order approach,the dynamic magnification factor (denoted by R )of the tall steel structure with Multiple Tuned Mass Damper has been formulated The criterion for the optimum searching then is the minimization of the minimum values of the maximum dynamic magnification factors(i e Min Min Max R ) Through the optimum searching ,the optimum parameters and indices reflecting the effectiveness of MTMD can be obtained Taking the different values of the first modal period and the mean wind velocity at 10m above the ground into account,a study has been conducted to evaluate their influence on the optimum parameters of MTMD and its effectiveness |
