Description
This guide for determining the fire resistance of concrete elements is a summary of practical information intended for use by architects, engineers, and building officials who must design concrete structures for particular fire resistance or evaluate structures as designed. The guide contains information for determining the fire endurance of simply supported slabs and beams, continuous beams and , floors and roofs in which restraint to thermal expansion occurs, walls, and reinforced concrete columns. Information is also given for determining the fire endurance of certain concrete members based on heat transmission criteria. Appendices giving the properties of steel and concrete at high temperatures and temperature distributions within concrete members exposed to fire are also included. A selected bibliography is included.
Keywords: acceptability; beams (supports), columns (supports); compressive strength; concrete slabs, creep properties; heat transfer; fire ratings; fire resistance; fire tests; masonry walls; modulus of elasticity; normalized heat load; prestressed concrete; prestressing steels; reinforced concrete; reinforcing steels; reliability; stress-strain relationship; structural design; temperature distribution; thermal conductivity; thermal diffusivity; thermal expansion; thermal properties; walls.
