DescriptionSouthern Pine boltwood is in abundant supply, but it contains high proportions of juvenile wood, and hence utilization for structural purposes is difficult when conventional means of conversion are employed. As a different approach, it is proposed that heart-center cants be cut from coltwood and then sliced into thick veneers for assembly into beams. The veneers can be expected to exhibit a considerable range in stiffness. It is hypothesized that stiff veneers are stronger in tension and compression than less stiff veneers, and that this attribute can be used to advantage by locating the stiffest veneers in the outermost portions of laminated beams.
