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

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

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

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

1.5 The 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.

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

1.7 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.
