The article presents the results of the wide-scale fire tests of light thin-walled steel structures (LTWS) for a fire protection efficiency of a structural fire-protection. Cross sections of steel constructions are composite. They consist of cold-formed galvanized C-shaped profiles lined with the basalt roll MBOR material. Then there is a numerical investigation by the finite element method in the Elcut PC. As a result, temperature-time curves of steel constructions are obtained under the mode of a standard fire both in experimental tests and in numerical studies. The results show good convergence of the finite element method to the experimental data. The influence of a facing layer thickness of the basalt roll MBOR material on the fire resistance to the fire influence on LTWS is estimated. Some groups of a fire protection efficiency of a structural fire protection are determined. It was found that the fire resistance of LTWS increased from 45 to 75 min due to the facing with rolled fire-resistant mineral wool materials.
