Title of the articleOn the calculation of the steel-concrete slab as orthotropic plate
Abstract.Methods for calculating the steel-concrete structures nowadays are insufficiently elaborated. Existing methods either use a beam model or semi empirical, or reflect the actual work of steel reinforced concrete slab as a spatial reference system . In this article, the steel-concrete overlay consisting of the concrete slab and the steel ribs regarded as a spatial construction, working in the direction of the steel beams – the edges and in the perpendicular direction. Resolved steel-concrete joists, supported by steel beams and loaded uniformly distributed load is represented as orthotropic plate. On the basis of kinematic hypotheses and conjectures recorded normal expressions for displacements and deflections. Using the method of averaging (homogenization) obtained characteristics of the concrete slab and deformation characteristics reflecting layers of shelves and walls of the I-beam steel beam. Recorded differential equation of bending of steel reinforced concrete slab as an orthotropic plate, which consists of four layers. Given expression to determine the bending characteristics of the model orthotropic plate. The formulas for determining the stresses in the steel beam and concrete slab are given. An example of calculation of steel reinforced concrete slab dimensions 6x6 m, supported by six steel beams of the I-beam № 20.
Keywords.Steel-concrete joists, orthotropic plate, differential equation, numerical calculations.
