【 摘 要 】

The paper describes effective constructive fire protection of steel corrugated beams by using large sheet and slab cladding. It introduces a scheme of fire-resistant steel beams with contact connection of elements of sheet and slab cladding to a steel bearing core. The study provides analytical equations of thickness of sheet and slab cladding with account of required fire resistance. The technical result of the new design solution includes increase of reliability of cladding elements fastening by means of fastening screws with a countersunk head and a pointed end, weight reduction of large size cladding materials and steel, reducing cross-sectional area of fire-resistant beams, increasing actual fire resistance of steel beams, reducing the risk of steel beam failure in the initial stage of fire and direct losses.
