This practice details the standard procedures for establishing the allowable properties for structural glued laminated timber (glulam). Allowable properties include: stress indexes; stress modification factors associated with slop of grain; stresses for bending, tension and compression parallel to the grain; horizontal shear; compression perpendicular to the grain; radial tension and compression stresses in curved members; grade adjustment factors; modulus of elasticity; and modulus of rigidity. This practice is limited to the calculation of allowable properties subject to the given procedures for the selection and arrangement of grades of lumber of the species considered. It does not cover the requirements for production, inspection and certification, but in order to justify the allowable properties developed using procedures in this practice, manufacturers must conform to recognized manufacturing standards.
