Beam String Structrue Spokes Roof Engineering Prestressed Construction Technology Research

The Beam string structure is spokes nearly ten years rapiddevelopment and application of a new type of long-span space structure.By the flexural stiffness of the structure of large component (also calledrigid components, usually for the beam, the arch or truss) and high intensitystring (also called the flexible components, usually for the cable connectsthe two poles) and composed; Through the flexible components exerttension, make the component become interconnected with overall rigiditystructure.This paper mainly through the finite element analysis softwareANSYS to assist simulation studies a stadium Beam string structure spokesof the prestressed construction technology, through the simulation analysisand comparison, certain economic and reasonable prestressing tensionscheme. Prepare a detailed implementation plan, and the construction ofprestressed construction difficulties puts forward appropriatecountermeasures. According to the construction plan and track the entireconstruction process, analysis of structure with the construction of key response change data. Through the construction monitoring, got Beamstring structure key nodes, implement the displacement and cable force anddisplacement double control to ensure superpositioning cable tensionduring and after the completion of the tension cable force and the structuraldisplacement and theoretical analysis, and finally achieve the consistentBeam string structure of the established construction goal.
