Fire Resistance of Ceiling Slab Concreted in Trapezoidal Sheet

In the paper the heat exposure and structural response model of reinforced concrete ceiling concreted into trapezoidal sheet is analysed. Temperature within the cross-section and in reinforcement is determined on the basis of European standards for fire design of concrete structures and steel-concrete structures using available formulas. Mechanical load is stated for accidental design situation. Fire resistance is assessed for structural resistance and insulation criteria.
