ASTM D 6555 : 2023 : REDLINE

1.1This guide identifies variables to consider when evaluating repetitive-member assembly performance for parallel framing systems.

1.2This guide defines terms commonly used to describe interaction mechanisms.

1.3This guide discusses general approaches to quantifying an assembly adjustment including limitations of methods and materials when evaluating repetitive-member assembly performance.

1.4This guide does not detail the techniques for modeling or testing repetitive-member assembly performance.

1.5The analysis and discussion presented in this guideline are based on the assumption that a means exists for distributing applied loads among adjacent, parallel supporting members of the system.

1.6Evaluation of creep effects is beyond the scope of this guide.

1.7This guide does not purport to suggest or establish appropriate safety levels for assemblies, but cautions users that designers often interpret that safety levels for assemblies and full structures should be higher than safety levels for individual structural members.

1.8The 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.

1.9This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.10This 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.
