ASTM D3737-04
Historical Standard: Standard Practice for Establishing Allowable Properties for Structural Glued Laminated Timber (Glulam)
ASTM D3737
Scope
1.1 This practice covers the procedures for establishing allowable properties for structural glued laminated timber. Properties considered include bending, tension and compression parallel to the grain, modulus of elasticity, horizontal shear, compression perpendicular to the grain and radial stresses in curved members.
1.2 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.
1.3 Requirements for production, inspection and certification are not included, but in order to justify the allowable properties developed using procedures in this practice, manufacturers must conform to recognized manufacturing standards. Refer to ANSI/AITC AI90.1 and CSA 0122.
1.4 Allowable properties established by use of this practice are based on dry conditions of use (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.
