Experimental Study On Steel Light—Weight Aggregate Concrete Combination Laminboard

Steel-concrete composite structure, the structure as a new form of rapid application development at home and abroad,it can give full play to steel tensile and compressive strength of concrete advantages,which broader applications.This paper another new combination plate:Steel-lightweight composite slab.the structure of light-weight,high strength,good seismic performance,construction and easy,and solve the corrosion resistance of steel structures and the short comings of poor.Through broad access to information, the paper steel-concrete composite hollow plate, a series of theoretical analysis and the use of elasticity theory, plasticity theory to derive the simplified combination plate bending capacity and deformation formula.Of steel-concrete composite hollow plate static test, analyze its force characteristics.The main test test loads at all levels of steel and concrete strain, the interface slip, plate deflection and crack the case and so on.Through controlled trial results and theoretical results, we found that, according to simplify the theory of plastic ultimate load calculated consistent with the experimental values better, and in accordance with the conversion method from the interface deflection is less than the experimental values, which shows the relative sliding interfaceshift of the plate deformation can not be ignored.Slip is derived when the deflection equation, calculated according to different boundary conditions the solution of differential equations.Experimental verification of the deflection of the formula is reliable.Plate finite element software for nonlinear analysis, and results with the theoretical results, test results were compared, agreement is better, the perfect steel-hollow lightweight design combined with a certain reference value.
