scope:

1. Scope

1.1 This practice covers the procedures for establishing allowable design stresses for structural glued laminated timber. Properties considered include bending, tension and compression parallel to the grain, modulus of elasticity, horizontal shear, and compression perpendicular to the grain.

1.2 This practice is limited to the calculation of design stresses for glulam subject to the given procedures for the selection and arrangement of grades of lumber of the species considered.

1.3 Requirements for production, inspection, and certification are not included, but in order to justify the design stresses developed using procedures in this practice, manufacturer must conform to recognized manufacturing standards for glulam. Refer to ANSI/AITC A190.1 and CSA 0122.

1.4 Stresses established by use of this practice are based on dry conditions of use (12 % average with less than 16 % moisture content). Modifications for wet-use conditions are given in 9.2.

1.5 The values stated in inch-pound units are to be regarded as standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
