The Stress-Strain State of a Steel-Reinforced Concrete Slab using a Profiled Sheet as Part of the Floor of a Building
Abstract: The paper presents the calculation methodology, modeling and assessment of the stress-strain state of a steel-reinforced concrete slab and using fixed formwork from a profiled sheet with a plan size of 2×0,5 m in the assembly and operation stages. The calculated moment of crack formation in the steel-reinforced concrete slab is determined, the possibility of resistance due to the adhesion forces of concrete with the sheet without the installation of additional stops and anchors is identified, the suitability of the structure under study for groups of limiting states is determined. The analysis of the results obtained in the PC «LIRA SAPR 2016». A theoretical range of permissible loads is revealed for which cracking does not occur. The diagram of the distribution of arising deformations along the height of the normal section of a steel-reinforced concrete slab is considered. Conclusions are made on the bearing and deformation capabilities of the investigated design.
Keywords: slab, profiled flooring, concrete mix, load, shear forces, anchoring, deformation.
