1、Designation:D767214Standard Specification forEvaluating Structural Capacities of Rim Board Products andAssemblies1This standard is issued under the fixed designation D7672;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of l
2、ast revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONRim board assemblies are an engineered component within light-frame wood platform construction.Rim board assemblies serve i
3、n multiple structural capacities,including:providing floor closure anddiaphragm attachment,transferring vertical and in-plane lateral loads,restricting out-of-plane rotationand lateral translation at the ends of the floor joists,providing deck ledger attachment,and spanningwall openings as a header
4、material.Rim board products,which serve a principal role as a componentintegrated within a rim board assembly,can vary by wood species,size,shape,and type.Rim boardproducts and assemblies require evaluation of their mechanical properties,physical properties,andtheir response to end use environments.
5、Procedures established in this Specification provide a meansto test rim board products and assemblies,to judge their acceptability,and to establish allowabledesign capacities.1.Scope1.1 This specification provides procedures for testing andestablishing the structural capacities of proprietary rim bo
6、ardproducts and assemblies for use in light-frame wood construc-tion using I-joist or structural composite lumber joist framing.This specification does not apply to commodity rim boardproducts.1.2 This specification was developed in light of currentlymanufactured panel,structural composite lumber,an
