Optimum Design of multiple tuned mass dampers for vibration control of asymmetric buildings
This study proposed a design procedure to determine the optimum location,moving direction,and optimal parameters of multiple tuned mass dampers(MTMD)for vibration control of irregular as well as symmetric buildings under dynamic loadings.For practical applications,based on the proposed procedure,a computer software was developed to be a postprocessor of any commercial structural analysis program,such as ETABS,SAP2000,and so on.First,the modal parameters reflecting building torsion-coupling(TC)behaviour were generated from the finite element model of the target structure.The optimum location,and moving direction of the MTMD system can be determined from the controlled mode shape.Then,the optimal parameters of the MTMD system were calculated by minimizing the meansquare modal displacement response of controlled mode.To investigate the MTMDs control performance,the responses of the building with and without MTMD system were compared under different excitations.Simulation results show that the proposed optimal design procedure is useful and practical to design MTMD systems for vibration control of irregular buildings under general dynamic loadings and is feasible for real implementation.
