Abstract

The construction of high-rise buildings has revealed new problems related to fire safety. The peculiarity of the architecture, which is covered in high-rise, in fires creates a danger for a large number of people there, reduces the possibility of their evacuation and rescue. The multifunctionality of such buildings, taking into account the originality of the external and internal views, leads to the difficulty of choosing a constructive system, a large number of utilities and technical systems. To address the issues related to safe operation, stay and evacuation of people is the development of a fire protection system for high-rise buildings, based on the development of: • measures to ensure the durability of buildings or parts thereof againstprogressive collapse due to * ensuring the fire resistance of structures and buildings; • measures to limit the spread of fire in high-rise buildings through theinstallation of fire barriers inside the building and the device of fire breaks between buildings; • measures for ensuring timely and unimpeded evacuation of people andtheir rescue at emergency in high-rise buildings; • systems of active protection of buildings from fire, namely: fire alarm andfire fighting, strong points of fire extinguishing.

Highlights

Every year in the cities of Russia increases the number of high-rise residential and multipurpose buildings, the height of which exceeds 75m [1]. The construction of such buildings revealed new problems related to fire safety
The fire resistance limit is the ability of structures in a fire to maintain technical characteristics within a certain period of time for which people will be evacuated from the building
For quantitative characteristics adopted "fire resistance limit" - the time period measured in minutes, from the beginning of the loss of design specifications and to reach the limit States [5]

Every year in the cities of Russia increases the number of high-rise residential and multipurpose buildings, the height of which exceeds 75m [1]. The peculiarity of the architecture, which lies in the increased number of floors, in case of fires, creates a danger for a large number of people there, reduces the possibility of their evacuation and rescue.
