Design method for wind-induced vibration control of high-risebuildings with hybrid tuned mass dampers

Based on the calculation method of wind loads in Chinese design code GB 50009—2012 ‘Load code for the design of building structures’, the practical design method for wind-induced vibration control of regular high-rise buildings with active/passive switchable hybrid tuned mass dampers (TMD/ATMD) was proposed. According to the equivalence of the vibration response variance, the control effect of TMD/ATMD system on the structure was attributed into the additional damping ratio. The formulas of the optimal parameters and the additional equivalent damping ratios were derived. The simplified calculation methods of average stroke ratio of inertial mass, active control force, rated power of the driver were proposed and the control modes switching criteria were discussed. Finally, this method was applied in wind-resistant design of the benchmark structural model controlled with TMD/ATMD system. The case study shows that the proposed design method can be used to analyze the response of the controlled structure and the preliminary design of the control system. Hybrid tuned mass damper can effectively reduce the equivalent static wind loads and dynamic response of the structure.
