Abstract:

The report analyses the requirements for walls with fire performance, viewed through the prism of Regulation No. Iz-1971 on the Construction and Technical Rules and Norms for Fire Safety in the Republic of Bulgaria. It provides detailed information regarding the classification of fire resistance and reaction to fire. Lightweight partition structures and the determination of their maximum permissible construction height are thoroughly discussed. The relationship between fire resistance classification and factors such as load-bearing capacity, space layout, intended use, and wall material is discussed.

Keywords:

Fire performance of walls, fire resistance of walls, reaction to fire of walls, maximum height of walls
