【 摘 要 】

This paper presents an analysis of the main member of a steel frame in a fire situation. The authors of this article used prescriptive rules and simple calculation models to present an impact of the roof bracing on the fire resistance of a rafter. Designers often have problems with the fire protection of the roof bracing made of steel round bars (Ø). This article presents a solution to this problem.
