Title of the articleTo the evaluation of the strength of the composite steel-concrete slab with pre-stressed beams and slab
Abstract.Problem statement. The stress state of the overlap consisting of pre-stressed beams arranged with a certain pitch and combined by a plate prestressed in the transverse direction under the action of operational loads is investigated. Expressions for estimating the strength of overlap with ribs are presented, when in stressed beams the stressed reinforcement is located along the I-beam shelves and along the envelope of the moment diagram. The aim of the article is to investigate the stress state of overlapping under different pre-stresses of ribs-beams and prestressing of the slab itself. Results. The analysis of theoretical studies of prestressed ribbed ferroconcrete overlappings made it possible to trace a number of principal positions of the stressed state of overlapping with ribs and will help to use them both in studies of composite slabs and they can be used in projects of composite floors of new buildings and reconstructed floors of architectural monuments of old construction. Conclusions. The data of the stressed state of the overlap consisting of beams and slabs in a complex section are obtained, as with prestressed beams and their influence on a conventional plate, and when prestressing the slabs and its joint work with prestressed beams.
