Abstract
The essence of the proposed innovative method lies in the fact that the testing of a monolithic reinforced concrete beam slab of a building is carried out without destruction, according to a set of single quality indicators, while evaluating their value using statistical control. To do this, the geometric dimensions of the beam slab, the heating scheme of the design section under fire conditions, the placement of reinforcement in the section, the depth and degree of its fire protection, the rate of thermal diffusion of concrete, the value of the test load on the monolithic beam reinforced concrete slab and the stress intensity in the rods of the longitudinal working reinforcement are determined. Application of the proposed method will determine the actual fire resistance of a monolithic reinforced concrete beam floor slab without full-scale fire exposure.
