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

The key requirements of building codes for the bearing structures fire safety of high-rise buildingswere 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 basedon the modern data about a fire load in the living units. This will lead to more cost-efficient building practice.
