Investigation of the Actual Operation of Steel-Reinforced Concrete Slab Structures Using Profiled Flooring
Abstract: The paper provides an analysis of the actual work of the stress-strain state of a steel-reinforced concrete slab using a fixed formwork from a profiled sheet with dimensions in plan 2,0×0,5 m. Experimental studies were carried out, the ultimate goal of which was to determine the minimum value of the load distributed over the area of the slab, at which the first cracks appear in its extended zone. The bending moment of cracking in the investigated steel-reinforced concrete slab was determined. The serviceability of the steel-reinforced concrete structure has been determined for two groups of limiting states. A comparative analysis of the results obtained with the calculated data in the software package «LIRA SAPR 2016» is carried out. The real load at which cracking occurs in the investigated structure is revealed. Exhaustive conclusions are made on the bearing and deformation capabilities of the structure under study without installing additional reinforcement.
Keywords: experimental studies, slab, profiled flooring (corrugated board), concrete mix, load, shear forces, deflection, crack formation moment.
