| Popis: | The publication is devoted to the study of the work of monolithic reinforced concrete floor with shaped steel profiles in two directions. Theoretical and experimental studies on models of the plate were made. To evaluate the stress-strain state of the slab reinforced with profiled flooring during operation, under the action of a uniformly distributed load, the theory of structurally orthotropic slabs supported along the contour was used. A technique has been developed for determining the bearing capacity of a slab based on the method of limiting equilibrium. The field of application of the developed methodology for calculating square and quasiquadratic monolithic plates with steel profiled flooring is substantiated. Putting into practice the construction of these floors, designed taking into account their work in two directions, can reduce the consumption of steel (steel beams) up to 50%, concrete up to 8% and labor at the construction site up to 22% per 100 m2 of the covered area compared to the calculation of the proposed structures according to the beam scheme. These structures are recommended for use in coatings and ceilings during the reconstruction of buildings, as well as in new construction. |
