Metal structures, as you know, have a number of advantages over other building materials used in load-bearing and enclosing structures, namely: low weight, unification of products, convenience and speed of erection of frames directly on the site and next to others. However, they also have disadvantages: low corrosion resistance and fire resistance of structures. At the design stage of load-bearing metal structures of buildings and structures, it is necessary not only to ensure their strength, stability and geometric invariability during the operation of the object under normal operating conditions, but to justify the preservation of these properties when the building is exposed to high temperatures during a fire by setting the building structures fire resistance limits corresponding to the fire resistance of the designed object. The known methods for assessing the fire resistance of steel structures and the standardized indicators of the fire resistance limits do not always give an unambiguous answer. In connection with these circumstances, the article proposes to consider the results of a comparative analysis of methods for assessing the fire resistance of a truss truss of a frame-bonded metal frame
the degree of fire resistance of buildings, fire resistance of building structures, load bearing capacity, methods for assessing the fire resistance of building structures
