Structural Performance of COM-PLY Studs Made with Hardwood Veneers. COM-PLY Report 16

摘要

This report is one of a series on the possibilities of producing house framing and structural panels with particleboard cores and veneer facings. COM - PLY 2 x 4 studs made with veneers of yellow - poplar, sweetgum, and white oak were tested for strength and stiffness, nail - holding properties, modules of elasticity of component parts, static bending, and compression parallel and perpendicular to the grain. All tests were conducted according to performance standards for composite studs used in exterior walls or American Society for Testing and Materials (ASTM) standards. Results indicated that the tested properties of COM - PLY 2 x 4's with any of the three hardwood veneers are comparable to those of COM - PLY 2 x 4's with southern pine veneers and to 2 x 4's of solid wood. Furthermore, COM - PLY studs made with the three tested species of veneer can be used with standard fasteners in common applications. Allowable load values per nail equal or exceed values found for spruce studs. Tabular data, graphs, and 11 references are provided. (Author abstract modified).
