Fire testing of wall assembly based on ASTM E 119 provides four performance criteria that need to be met: Resistance of wall assembly against heat transmission through it. Resistance to the travel of flame or hot gasses through the wall adequate to start fire and burn cotton waste on the other side of the wall which is not exposed to fire.
The resistance of concrete masonry to fire is well established by extensive testing to be a function of the type of aggregate used in the manufacture of the masonry units and their equivalent thickness.
The calculation method is fully described in ACI 216.1/TMS 216 and IBC Section 722, and determines fire resistance ratings based on the equivalent thickness of concrete masonry units and the aggregate types used to manufacture the units.
load test that follows. Fire endurance can be calculated as a function of the aggregate type used in the block and the equivalent sol. Fire-rated walls made of gypsum wallboard are not required to endure the same fire-hose test. e evaluated in two ways. The "Equivalent Thickness" method is outlined in detail in Appendix D o.
This standard describes acceptable methods for determining the fire resistance of concrete building and masonry building assemblies and structural elements, including walls, floor and roof slabs, beams, columns, lintels, and masonry fire protection for structural steel columns.
Fire resistance of concrete masonry walls is a function of aggregate type and equivalent thickness of the masonry units. The ratings in the charts below are calculated using the actual percent of solids in the various sizes of blocks as manufactured by Capitol Concrete Products.
The National Construction Code - Building Code of Australia (NCC-BCA) requires that walls be designed in accordance with AS3700, Masonry structures code to provide the required Fire Resistance in buildings. The Fire Resistance Levels (FRLs) required by the NCC-BCA for walls is summarised in Table A.
