This standard describes acceptable methods for determining
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 determining
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. Masonry construction
shall comply with TMS 402/ACI 530.1/ASCE 6
