ASTM D5457-21 - 1.4.2021
 
1. Scope

1.1?This specification covers procedures for computing the reference resistance of wood-based materials and structural connections for use in load and resistance factor design (LRFD). The format conversion procedure is outlined in Section 4. The test-based derivation procedure is outlined in Annex A1. The reference resistance derived from this specification applies to the design of structures addressed by the load combinations in ASCE 7-16.

1.2?A commentary to this specification is provided in Appendix X1.

1.3?The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
