Study The Supporting Capacity Of Steel Deck-concrete Composite Slabs And Combination Truss Beam In Integra Web Steel

The structure is used to undertake the dead weight and function load. The dead weight can't be got rid of from the structure, removing the structure useless for supporting capacity can greatly enhance the supporting capacity of the structure and save the cost. Having known the characters of the solid abdomen beam, people begin to remove some material in abdomen of the beam, thus the plane truss beam is formed. Integra Web Steel is composed of the plane truss beam.The plane truss beam has its fatal weakness that its flexible rigidity outside plane is very small and loses stability easily and can't use material intensity well, so some measure must be taken to avoid losing stability.The steel deck-concrete composite slabs on the truss beam can avoid losing stability in Integra Web Steel. When the steel deck-concrete composite slabs is well combined with the truss beam, the combination truss beam is formed, not only it can avoid losing stability, but also it can let the concrete intensity be used well, thus it will enhance the supporting capacity and rigidity greatly.The main goal of this article is to analyse the supporting capacity of the ceiling of Integra Web Steel while combination effect is considered. In this article there are two aspects, one is about steel deck-concrete composite slabs, the other is about combination truss beam.The work and characteristic as follows:(1) Introduce Integra Web Steel and steel-concrete combination structure.(2) Introduce the details of Integra Web Steel, then get the models of steel deck-concrete composite slabs, truss beam and combination truss beam.(3) Introduce the composite ceiling theory, for comparing the supporting capacity from theory with that from the ANSYS software.(4) Study the supporting capacity of steel deck-concrete composite slabs by use of the ANSYS software, and get the effects of all kinds of factors and analyse the reason from the theory. Finally compare the supporting capacity from the ANSYS software with that from the theory.(5) Study the supporting capacity of one truss beam and all kinds of composite beams of this beam by use of the ANSYS software, and get effects of all kinds of factors and analyse the reason from the theory.
