| Title of the article | Calculation of steel-reinforced concrete slabs with steel profiled decking |
| Abstract. | Analyzed national experience of recovery floors of old buildings, which are mainly monuments. It was stressed that the earlier the overlap in our country is carried out mainly in wooden form. Today, after a lifetime, they either lost the carrying capacity, or supervisory authorities require their replacement with safer designs in terms of their fire resistance. Composite structures are most suitable from the point of replacing the light beams on fire safety and reliability. The article deals with the composite slab based on the steel sheeting. Analyzed the existing design rules and calculation methods for composite slabs with steel floorings. The method of calculation, based on the calculation model reflects the actual work of composite structure diagrams, and taking into account the real strain and stress. We consider two types of cross-sections calculated on the basis of the best possible options for the structural elements of restored ceilings. Given an expression to determine the boundaries of the compressed composite sectional area by taking into account the compliance of contact between the steel beam and slab (concrete + steel decking). The formulas for determining the torque of the internal state of a flexible composite element, write the condition of strength calculation section. The use of advanced methods of calculation of composite slabs with steel decking will facilitate the introduction of these constructs into the practice of reconstruction and new construction. |
