ABSTRACT Structural columns are characterized by a composite outer layer of thin wooden laminations formed into a hollow, cross-sectional shape,composed of two substantially identical pre-fabricated halves, each having longitudinal margins defined by a formed shoulder terminating in a dia- gonally disposed edge abutting with a corresponding edge of the other layer half to form a continuous corner. The column also includes a-t least one composite inner layer formed into a hollow, cross-sectional shape corresponding to the cross- sectional shape of the outer layer and sized to fit within and closely underlie the outer layer. The inner layer is also composed of two, substantially identical pre-fabricated halves each having longitudinal margins defined by a formed shoulder terminating in a diagonally disposed edge. The two inner halves are joined together along their edges to define a closed, hollow form. In the manufacturing process, a plurality of formed inner and outer column layer halves are integrally constructed from flat sheets of wooden laminate simul- taneously bonded together and molded into a triangularly shaped wave pattern.
