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).
