Новые требования к огнестойкости строительных конструкций и средств огнезащиты

Abstract

Set of the new requirements for ensuring fire resistance of the building structures and means of their fire protection described in the article was developed considering the provisions of the Federal Law № 123-FZ of July 22, 2008 «Technical Regulations on Fire Safety Requirements» and Technical Regulations of the Eurasian Economic Union «On the Requirements for Means Ensuring Fire Safety and Fire Extinguishing» (TR EAEU 043/2017). As part of the studies, the need was substantiated in applying more detailed and differentiated requirements to the fire resistance limits of the load bearing, self-supporting and enclosing building structures, as well as to the individual parts of the structures and their junctions — light-transmitting elements, inter-floor belts, partition wallы, expansion joints, etc. The set of new requirements on ensuring fire resistance of the building structures includes the requirements for building structures fire resistance limits that are not specified in Table 21 of the Federal Law № 123-FZ of July 22, 2008 «Technical Regulations on Fire Safety Requirements», as well as unambiguous interpretations of the provisions of this Table in relation to both individual structures and the elements of these structures. The developed requirements also supplement and disclose the number of provisions of the Federal Law № 123-FZ of July 22, 2008, regarding the choice of the method of testing building structures for fire resistance, the design of fire walls, the limits of fire resistance of the junction points, etc. As part of the conducted studies, the new provisions were substantiated that regulate the use of fire protection means for the building structures based on the fire protection project and differentiated methods for assessing the fire resistance limits of steel structures with fire protection.
