This standard describes acceptable methods for determining the fire resistance of concrete building and masonry buildingassemblies and structural elements, including walls, floor and roof slabs, beams, columns, lintels, and masonry fireprotection for structural steel columns. These methods shallbe used for design and analysis purposes and shall be based on the fire exposure and applicable end-point criteria ofASTM E 119. This standard does not apply to compositemetal deck floor or roof assemblies.
The primary intended use of this document is for determining the design requirements for concrete and masonry elements to resist fire and provide fire protection. Tolerance complianceto the provisions for concrete shall be based on information provided in ACI 117. Consideration for compliance to theprovisions for masonry shall be based on the informationprovided in ACI 530.1/ASCE 6/TMS 602.
Methods other than those presented in this standard shallbe permitted for use in assessing the fire resistance ofconcrete and masonry building assemblies and structuralelements if the methods are based on the fire exposure andapplicable end-point criteria specified in ASTM E 119.Computer models, when used, shall be validated and supportedby published material to substantiate their accuracy.
