Beam Conversion. High-rise Building Structural Design Analysis And Applications

In recent years, with China's sustained and rapid economic development, high-rise buildings also have a rapid development ,it toward to the direction of the complex, diverse functions and internal space changing, and the complexity ranks has among the world's highest. In one building, the function of the building will bring complex interchange along the direction of the high, the upper floor can be used for the hotel and residential, the central floors for office space, and the lower floors for the shops, restaurants and cultural facilities; but the normal layout and the function are contrary to the building space requirements in structure, Therefore the structure must set the level conversional component, namely transfer floor structure. The transformation level structural engineering has become one development trend of the modern high-rise construction structure.Because of the transfer layer, the uniformity of stiffness will be greatly damaged along the height of buildings, lead to the transmission line complicated and deformation and stress concentrated. It decides that the transfer layer structure is unusually to conduct analysis and design.This paper synthesized the experiments and theoretical research of the transfer layer structure, introduced the current situation and the development trend, analysed and discussed the function and classification, structure and design principles of the transfer layer structure. Among them, the advantages of the beam conversion layer structure is clear ,direct and the transfer means clear, and it is facilitate to the analysis , design and construct of the project, and it can save more money, suitable for the large space shear wall structural system at the bottom.Based the project of Zheng Hong flag in Zhengzhou, this paper focuses on the concept design, seismic analysis, stiffness analysis and the overturning resistance analysis in the beam conversion structure, and it analysis the stress and deformation of the floor flat. This paper try to provide the theory support for the form of practical application and it look forward to the follow-up research.
