Fire resistance of monolithic reinforced concrete structures of the tall residential building with core structural system

Пожарная безопасность в строительстве

The key requirements of building codes for the bearing structures fire safety of high-rise buildings were identified. Heat-transfer and structural calculations were carried out for reinforced concrete monolithic pylon and floor slab of the building. Three different fire curves were implemented – the standard one and two real ones. It was established that for high-rise residential buildings a fire resistance limits of its structures should be determined based on the modern data about a fire load in the living units. This will lead to more cost-efficient building practice.
