Steel Sheeting And Concrete Composite Board Structure Analysis And Calculation Of Theoretical Research

On the basis of relative researches in the world, according to the study status of steel-concrete composite slab, which would be widely used in modern bridge, modified equivalent inflexibility of steel-concrete composite slab was deduced by use of conversion section principle in this paper; Based in this, this paper put forwards the theory of ultimate flexural capacity of steel-concrete composite slab in consideration of slip effect, and introduces the practical simplified method for calculating flexural deformation of steel-concrete composite slab in consideration of the effect of steel studs and welded wire, and conclude that the methods in this paper is veracious and reliable, comparing with the traditional calculating mode; Morever, this paper put forwards the calculating theory and program of the effect analysis of creep and shrinkage to steel-concrete composite slab, using conversion elastic modulus principle, and testifies that the theory is right and the program is reliable and practical .
