FIRE SAFETY REQUIREMENTS FOR HIGH-RISE PUBLIC BUILDINGS WITH A CONDITIONAL HEIGHT OF 100 M TO 150 M

Abstract

Based on the results of analytical research, fire safety requirements for high-rise public buildings with a conditional height of 100 m to 150 m inclusive during their design, in particular regarding the planning of the territory and placement of high-rise buildings, requirements for spatial planning solutions, design solutions and materials, engineering systems, fire protection systems, ensuring the safe evacuation of people. The paper outlines the provision of safety conditions for fire and rescue squadrons. The results of investigations during the consideration of measures to limit the spread of fire on the facade of buildings and the corresponding constructive requirements are given. Improved requirements for ensuring the functioning of internal fire water supply, automatic fire extinguishing systems, elements of water supply systems, including tanks with fire water supply are substantiated. The updated requirements for the external fire-fighting water supply system, the places of installation of fire hydrants and the places of connection of the outlet pipes of the dry pipes to the fire-fighting equipment are determined. Based on the analysis of foreign experience and own calculations, measures to prevent the vertical spread of fire between floors on the facade of the building are substantiated and examples of structural elements of fire eaves on the border of vertical fire compartments at the level of the floor are given. Research identified promising areas for further research to increase the level of fire safety to high-rise public buildings. The requirements included in the draft national standard of Ukraine were developed taking into account international experience in the design of such buildings and the current level of scientific and technological development in the field of fire safety
