Determination of Shear Stresses in Flexural Layered Reinforced Concrete Elements
When observing the technical specification, the concreting of layered monolithic reinforced concrete slabs with the use of haydite concrete and heavy concrete provides the reduction of their masses up to by 30% and reliable adhesion between haydite concrete and heavy-weight concrete. To clarify the parameters of the stress-strain state of overlaps, formulas for calculating shear stresses in layered bending reinforced-concrete elements at the stages of operation with cracks in the tension zone with due regard for the position of the neutral line have been obtained. The use of these formulas for determining the shear stresses in areas without cracks when finding the shear forces makes it possible to achieve the sufficiently accurate convergence of their experimental and theoretical values. The calculation of elements according to the deformed scheme with the help of these formulas makes it possible to reveal the nature of the shear stress distribution along the length of the element and the section height in areas with cracks and without them as well as to improve the convergence of experimental and theoretical values of deflections.
