Abstract:

The article presents and describes the methodology for determining the fire resistance limit state of loaded thermally stressed steel floor beams. The article describes the methodology for taking into account the uneven temperature distribution along the height of the cross-section of a fireproofed steel floor beam. The author presents a method for refining the stiffness characteristics of an I-beam after exposure to high temperatures from a fire and compares the results with the results of field tests.
