Figure 3-4. Elements of diagonal bracing.
LB = Total length (feet) of the brace member from end connection to end connection.
Lmax = The maximum allowable unsupported length of the brace (feet) due to buckling and bending. For all 2-
inch material, Lmax = 6 1/4 feet; for all 4-inch material, Lmax = 14 1/2 feet.
L = The actual unsupported length (feet) of the brace used.
