✦ Synopsis
For evaluating the fire-resistance stability of steel columns exposed to a red-heat furnace charge in safety pit in a nonferrous metal factory workshop, the temperature distribution of steel columns within the height of 10m is calculated by a hierarchy computing method based on heat radiation theories and heat transfer between the flange plate and the web plate. The numerical calculation result indicates that there are great differences between the temperature of the web plate and the flange plate. The influences of the height of the flange plate and the relative position between furnace charge and steel columns on the thermal are analyzed. The results offer some references for the Performance-Based Fire Protection Design of the nonferrous metal factory workshop.
