Dimension lumber compression members are inherently unstable because of small sectional dimensions relative to the unsupported length of the member. Point bracing is often used to reduce the effective buckling length. Buckling is a bending phenomenon which can be addressed through an effective moment of inertia of the built-up compression member. The effective moment of inertia for built-up members that are not rigidly bonded can be determined with a procedure adapted from the Forest Products Laboratory (Forest Products Laboratory, 1971). The effective moment of inertia is used to determine the critical buckling load (Fc *) used to determine the stability factor in the NDS design process (AF&PA, 2001). Analysis shows that for a 3.048m long 38.1mm by 139.7mm SP compression member that the T-braced capacity is 37% greater than that of a board braced at mid-length and 32% less than for a board third point braced. The T-bracing may also be used in conjunction with point bracing to combine increased effective moment of inertia with reduced buckling length.
