【 摘 要 】

Experience shows that the assessment of fire resistance of steel elements based on European standards is conservative, while advanced methods are complex and time consuming. The analysis of existing methods for the tested steel beam exposed to bending and standard ISO fire was conducted in the scope of the international Round Robin study. The comparison of results shows that advanced methods provide non-uniform assessments. Nevertheless, advanced methods are necessary for improving standard methods that overestimate fire resistance of this "trivial" problem.
