Abstract

The temperature calculation of hollow steel sections at elevated temperatures is a well-documented and standard procedure. Through this standard procedure, the temperature can be calculated by assuming a uniform gas temperature all around the section, which is called a symmetric fire in this paper. Embedding in surrounding structures or connecting to another steel member results in non-symmetric heat distribution in the member. This non-symmetricity of the surrounding temperature may cause surface-to-surface heat radiation inside the
member, thus affecting the steel section temperature distribution. This effect is considered in this paper by adopting analytical and finite element method analysis.
