FIRE RESISTANCE OF REINFORCED CONCRETE SLABS ACCORDING TO EC2 AND BRANZ TR8

Concrete elements are practically an integral part of every construction project andbuilding. They have significantly higher fire resistance in comparison to elements madeof other construction materials. However, RC slabs are the most sensitive concreteelements to the effects of fire when compared to all the other reinforced concrete elements.Therefore, this research focuses on determining the fire resistance of RC slabs usingMethod for determining fire resistance of slabs BAS EN 1992-1-2:2017, Eurocode 2,Design of concrete structures, Part 1-2: Structural fire design (Tabulated Data) andBRANZ Technical recommendation No. 8 – Method for Fire Engineering Design ofStructural Concrete Beams and Floor Systems. A fire action to RC slabs is modeled usingstandard fire ISO 834-1 (BAS EN 1991-1-2:2015). This research considers determiningfire resistance of simply supported RC slabs of different spans and different depths withvariations of concrete cover
