Purpose. The development of tabular data for estimating the fire resistance of bendable steel beams, taking into account the given level of loading.
Methods. The analytical solution of thermal and static problems of fire resistance of bendable steel structures.
Findings. For the range of steel W shaped I-beams (normal and wide flange according to STO ASCHM 20-93) from steel grades S245, S255, S285, S345 load limits are determined (depending on the span, section class and working conditions of the structure) at which the beam can be used in a building without fire protection, providing fire resistance of 15 and 30 minutes. Based on the calculations, tabular data were developed to assess the fire resistance of steel beams without fire protection.
Application field of research. The results obtained can be used to solve the problems of fire resistance of bendable steel beams, taking into account the load while designing and constructing buildings and structures.
