Abstract

A theoretical model and a solution scheme for studying the temperature distribution in steel structures exposed to a prescribed fire environment are presented. Radiation and convection as well as conduction of heat are taken into consideration. The method of orthogonal collocation is employed for the solution. Efficiency of the method as applied to the problem is demonstrated. Temperature distributions in rigid frames exposed to the fire environment specified by ASTM standard curve are examined. It is found that the temperature increases rapidly only in regions surrounding the fire loads. No appreciable temperature change takes place elsewhere in the structures. The effect of the fire environment is essentially local to the heat source. The methodology described herein is useful for the quantitative assessment of the fire resistance of structures.
