The author considers the main methods of fire protection for residential and public buildings and structures. The efficiency of metal structures is analyzed, the latest methods of corrosion and fire protection of metal structures are selected. For the plastering, cladding and coating methods, a table of the required thickness in relation to the fire resistance limits was compiled. Based on this table, graphical and empirical dependences for the 30k1 I-beam column are constructed, showing the dependence of temperature on time and the limits of fire resistance on the reduced coating thickness.
According to the graphic data, the most economical method of fire protection was chosen, but the resulting deflections exceed the limit according to current standards.
