Assessment of fire resistance of fireproof reinforced concrete structures

A finite-element model for the heat engineering calculation of fireproof reinforced concrete slab has been built, which is designed to assess fire resistance unprotected structures. feature correct choice types transfer in cavities ceilings. An algorithm that includes experimental and procedures determining structures applied. The initial, boundary conditions construction were formulated; thermophysical properties materials substantiated. Thermal multi-hollow ceiling under was carried out. adequacy developed checked. satisfactory convergence calculated temperatures with an accuracy 10 % established, would suffice calculations. built makes it possible Thus, there reason argue constructed can partially or completely replace assessment resistance, provided setting parameters are
