Abstract:
A reinforced wood laminate structural member built to bear large load forces applied over the span of an open area and withstand high interlaminar shear stresses to maintain the load-bearing capacity of the structural member, the structural member having a longitudinal axis and comprising:plural elongate wood segments attached to form a unitary structure, at least one of the wood segments having a length extending along the longitudinal axis;a fiber reinforcement having a length and including a multiplicity of fiber strands held within a resin casing having first and second major surfaces; andcellulose surface material having a resin-impregnated surface bonded to one of the first and second major surfaces of the resin casing of the fiber reinforcement and adhered to one of the wood segments to provide a cellulose surface material-to-wood segment interface that withstands high shear stresses and thereby maintains the load-bearing capacity of the structural member, the fiber reinforcement being positioned so that its length extends along the longitudinal axis of the structural member.
