Research And Applications Of A New-type TSS In Coordinate With Steel And Concrete

According to an engineering project, a new type of BBS is conceived in this paper----the structure of the composition of steel-concrete, It is improved on the baseof the large span prestress structure of TSS and its static behavior is analyzed.Prestress steel structure and truss string structure and combinations already gradual ly practise to various engineering by presenting the overview in the paper, and anlaysis its advancement and the corresponding problems from the development status, and thus conceive the new structural by integrating into the steel and concrete. The new type structure form the compose top truss through short grim column with the two materials of the steel and concrete.From an engineering perspective of the application, The suspension of the process of the new type structural involves the preparation of the state of zero, the initial appearance, load stage and cooperation load stage. through the calculation and comparison of the cut concrete panels cut to the lower reaches of truss contribution, research and analysis shows that the overall structure of the concrete slab in the work improve the overall structural rigidity evidently in cooperation stage.The steel structure design is presented, including stuctual style selection, structural calculating, design, ect. based on the aechitectural conception, such problems as choosing structural style,longitudinal structure rigidity, are discussed emphatically.In this paper,the new structure are analyzed by the finite element method with geometric non-linear structural analysis, limit capacity and the earthquake; some key techniques in computations and design of the new type TSS are analyzed,which have been adopted in pactice engineering. At the same time, from the concepts of mechanics,provide some simple ideas and analysis equations.In adition, the construction stages are taken into account as well by the linear finite element method. It was shown by computed examples that the deformation and the truss stiffness and the overall stability are improved effectively because of the adoption of the concrete slab.
