This standard provides requirements for determining fire resistance of concrete and masonry elements and assem-blies. Calculation procedures for determining fire resistance are provided for concrete walls, floors, roofs, and columns and masonry walls, lintels, and columns. Procedures are also included for determining requirements for concrete cover, protection of structural steel columns using concrete or masonry, and for hollow structural steel columns filled with concrete. Procedures for determining the contribution of additional fire resistance provided by finish materials on concrete or masonry assemblies are also included.
This standard describes acceptable methods for deter-mining the fire resistance of concrete and masonry building assemblies and structural elements, including walls, floor and roof slabs, beams, columns, lintels, and masonry fire protection for structural steel columns. These methods shall be used for design and analysis purposes and shall be based on the fire exposure and applicable end-point criteria of ASTM E119. This standard does not apply to composite metal deck floor or roof assemblies.
The primary intended use of this standard is for deter-mining the design requirements for concrete and masonry elements to resist fire and provide fire protection. Tolerance compliance to the provisions for concrete shall be based on information provided in ACI 117.
