Study On Dispersion Tube Structure System For High-rise Buildings

Dispersion tube structure system is a new structure system is bring forward to solve the conflict between high-rise building functions and its structure design. The structure use beams and floors to connect some small concrete tubes which are used to risist lateral load. Study the small concrete tube for simple rigidity formula.Finally,a model of the new system is anslysed in statics and dynamics method to get its excellences for the reference of structure design.Concrete tube is anslysed by material mechanics and fea method respectively to get its mechanics property, it shows that the results in material mechanics can satisfy engineering precision.For twist rigidity,the formulae which can elevate work efficiency are gotten through plentiful calculations.To study dispersion tube structure's mechanical characteristic as well as the feasibility to build high building in this new system,some tactic work is done:first,a fictitious model is framed;second,mechanics and displacement characteristic of the structure in gravity as well as in lateral wind load are researched;thirdly,mode analysis of the structure is done to get the dynamical identity;fourthly, mode-superposition response spectrum method is used to study the structure's Anti-earthquake performance.Finally,the merit of the new system is sum up for design reference.Finally,the results of this paper are summed up,and questions which need to be solved are pointed out.
