2012 IBC

722.6.3 Design of fire-resistant exposed wood

members. The fire-resistance rating, in minutes, of

timber beams and columns with a minimum nominal

dimension of 6 inches (152 mm) is equal to:

Beams:

2.54Zb [4 -2(b/d)] for beams which may be exposed to

fire on four sides.

(Equation 7-18)

2.54Zb [4 -(b/d)] for beams which may be exposed to

fire on three sides.

(Equation 7-19)

Columns:

2.54Zd [3 -(d/b)] for columns which may be exposed to

fire on four sides

(Equation 7-20)

2.54Zd [3 -(d/2b)] for columns which may be exposed

to fire on three sides.

(Equation 7-21)

where:

b = The breadth (width) of a beam or larger side of a

column before exposure to fire (inches).

d = The depth of a beam or smaller side of a column

before exposure to fire (inches).

Z = Load factor, based on Figure 722.6.3(1).
