Research on parameters of viscous dampers inserted in MSCSS

Mega-sub Controlled Structure System(MSCSS) is a new form of super high-rise building structural system.In this paper a new arranging scheme about the insertion of the viscous dampers is proposed according to construction features of MSCSS.The optimum damping parameters matching with the dynamic characteristics of MSCSS are introduced through investigating the dynamic responses of this structure system with the viscous dampers of different damping parameters subjected to rare earthquake.The results show that this scheme can effectively reduce the number of the viscous dampers and the acceleration response of MSCSS under the seismic load.Furthermore it can shorten the computation time.The bracing stiffness of the viscous dampers influences the scope of the plastic hinges appearing in MSCSS greatly.The capacities of anti-earthquake and anti-wind of MSCSS are increased by adopting the optimum parameters.The results have laid foundation for the further research of this new structure system.
