Scope

ISO 22389-1:2010 specifies the requirements for prefabricated wood-based I-beams used as structural members in bending applications.
It gives procedures for establishing and evaluating structural capacities of prefabricated wood-based I-beams. The capacities considered are shear, moment, stiffness, bearing, and flange tension and compression. Procedures for establishing common details are given and certain end-use considerations specific to wood-based I-beams are itemized.
