Abstract
Abstract
The article proposes the construction of a steel-concrete floor. Processes of making, modelling and testing of steel-polystyrene concrete beams and slabs are considered. The results of tests of prototypes are presented. During the tests, the stresses in the steel components of the beams and the deflections value of the plates were measured. The combined action of a thin-walled steel structure and polystyrene concrete is noted. As a result of the combined action of polystyrene concrete and a thin-walled profile, it was possible to more evenly distribute stresses in the metal profile. The destruction of the structure occurred due to the loss of stability of the upper profile belt between the anchoring points. Polystyrene concrete slab is recommended as a roof slab in residential buildings.
