FIRE PROTECTION SYSTEMS

W/D, A/P and M/D TABLES FOR STRUCTURAL STEEL SECTIONS W/D, A/P and M/D ratios provide a means of sizing structural members for the purpose of fire protection. Fire rated designs specify minimum steel sizes to which the rating information applies. The fire resistance ratings are applicable to larger structural components – those having greater W/D, A/P or M/D ratios than the member tested. Generally, as the W/D, A/P and M/D ratio increases, fire resistance increases and/or the required thickness of directly applied fire protection material decreases for a given rating.

For Imperial sizes W = Weight of steel section (lb./ft) D = Heated perimeter of steel section in inches (in.) For Imperial shapes A = Cross sectional area of steel section (in2) P = Heated perimeter of steel section in inches (in.) For Metric sizes: M = Mass of steel section (kg/m)

D = Heated perimeter of steel section in metres (m)

W/D = M/D x 0.017 M/D = W/D / 0.017 A/P = W/D x 144 / 490

The heated perimeter, D or P, is that portion of the perimeter of the steel cross section that could be exposed to fire. It depends on the dimensions of the steel section and its orientation to the fire. Beams supporting a floor or roof are assumed to be exposed to fire on “three” sides - the bottom and two sides. Columns and some bracing members are assumed to be exposed to fire on “four” sides or the perimeter of round members. These tables include W/D, M/D and A/P values for both three sided (beam) and four sided (column) exposures.

When required, the mass, weight or cross sectional area of steel section can be read from structural steel tables. When the cross sectional area of a steel section is known, its mass or weight can be calculated by multiplying that area by the density of steel (7850 kg/m3 or 490 lb/ft3). Examples

For a W shaped section, the heated perimeter is calculated as follows:

a) Beam, three sides exposed to fire D = 2d + 3b – 2w Where: d = depth of section b = flange width w = web thickness

Note: Certain applications, such as the equation for “Adjustment of Thickness of Sprayed Protection for Beams of Alternate Size” in ULC’s, ‘List of Equipment and Materials’, ignore the web thickness (w) and calculate D = 2d + 3b.

b) Column, four sides exposed to fire D = 2d + 4b – 2w

Where: d = depth of section b = flange width

w = web thickness Values of D and P may likewise be calculated for other shapes and orientations by considering the perimeter or surface area of the steel section and that portion of which could be exposed to fire.

How May W/D, M/D and A/P Rations be Used?

When the size of a structural member differs from the minimum size specified in a fire test design, compare the W/D, M/D or A/P ratios. If the W/D, M/D or A/P is greater than or equal to that of the test design, the fire resistance rating and method of protection (minimum thickness, etc.) are applicable to that member.

The UL “Fire Resistance Directory” and ULC “List of Equipment and Materials” contain equations for adjusting thickness of directly applied fire resistive materials for beams and columns of alternate size. The ratios from the attached tables may be substituted directly into those equations. Some fire resistance designs include proprietary thickness equations that utilize W/D, M/D and/or A/P ratios.
