Abstract


This publication introduces and describes the mechanical properties of a newly developed structural composite using corrugated veneer panels as core material. Prior to this study, rejected hardwood veneers and veneer residues (side-clippings) were converted into three-dimensional panels, and the basic physical and mechanical properties were investigated through the testing of similar, but non-corrugated products. This study focuses on the application of I-joist web elements, although other application possibilities are also mentioned. Different web to web and web to flanges joints were configured and tested for their tension and shear strength resistance. The load-bearing capacity was evaluated using standard structural size prefabricated members. The I-joists that had corrugated web panels showed an improved load carrying capacity under concentrated loads. Buckling failure, which is common in deep straight web panels of oriented strand board (OSB), or plywood, under concentrated loads could not be observed.
