Title of the articleNumerical and experimental studies of prestressed steel-reinforced concrete ribbed slabs and beam with prestressing reinforcement without adhesion to concrete
Abstract.Problem statement. The purpose of the research work is to analyze the research methods of prestressed steel-reinforced concrete beams and slabs with prestressing reinforcement without adhesion to concrete. The tasks are – the analysis of domestic and foreign technical literature on assessing the stress-strain state of prestressed steel-concrete and steel-reinforced concrete, both insulated beams and beams as part of a ribbed monolithic floor, both with reinforcement working together with concrete, and isolated, without connection with concrete. The task is also to assess the effect of transverse reinforcement of beams on the stress-strain state of a ribbed prestressed plate from longitudinal prestressed reinforcement located in the rib-beam, based on the analysis of existing approaches. Results. The main research results consist in analyzing the current approach in assessing the strength of steel-reinforced concrete beams and slabs, in identifying the stress-strain state of a prestressed bending steel-reinforced concrete and steel-concrete element consisting of a beam and a slab, in assessing the strength of prestressed beams as part of a ribbed floor with prestressed reinforcement without adhesion with concrete. Conclusions. The significance of the results obtained for the construction industry consists in identifying the stress-strain state of a bent steel-reinforced concrete element. The results of research, assessment of the strength of steel-reinforced concrete beams and floors can be used in the construction of ribbed slabs and beams of new buildings in steel-reinforced concrete, wood-concrete, precast-monolithic reinforced concrete versions and in the restoration of floors of buildings that have served their standard service life.
Keywords.steel-reinforced concrete structures, prestressed elements, stressed state, reinforcement without adhesion to concrete.
