ASTM D5055-12

Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists

ABSTRACT
This specification gives procedures for establishing, monitoring, and reevaluating structural capacities of prefabricated wood I-joists. Capacities considered are shear, moment, and stiffness. Procedures for establishing common details are given and certain design considerations specific to wood I-joists are itemized. Qualification is required for certain common details of I-joist application since they often influence structural capacities. All capacities are to be reported with three significant digits. Shear capacity qualification, moment capacity qualification, end joint qualification, stiffness capacity and creep qualification, and details of end use shall be established to meet the requirements prescribed. Design values are determined from the analysis and capacities as specified. The bearing capacity and regarded solid sawn lumber flanges shall be reevaluated to meet the requirements prescribed. The shear and flange material, and empirical moment capacity shall be tested to meet the requirements prescribed.
SCOPE
1.1 General—This specification gives procedures for establishing, monitoring, and reevaluating structural capacities of prefabricated wood I-joists. Capacities considered are shear, reaction, moment, and stiffness. Procedures for establishing common details are given and certain design considerations specific to wood I-joists are itemized.  
1.2 Contents of the Standard—An index and brief description of the main features of this specification are given in X1.1.1.  
1.3 Development of the Standard—The development and intent of this specification is discussed in Appendix X1.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5  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. A specific precautionary statement is given in 6.1.1.5.
