Plywood I-beams. by, , National Association of Home Builders edition, in English Plywood : Another consideration to keep in mind when you are specifying a beam is its resistance to bending. To compare built-up wood beams, I multiply beam width by beam depth squared, and then I divide the product by 6. A triple 2×10 beam has a bending-resistance factor of ; add plywood between the 2x10s, and the factor increases 15% to A.
The web serves to transmit the shear stresses, relying on plywood's panel shear capacity and dimensional stability. I-Beams are generally not considered to be an appearance product due to the visibility of gluelines but can be finished accordingly for architectural and design applications. ) shall be psi for plywood with minimum 5-ply, 5-layer panel construction; and psi for 3-, 4- or 5-ply, 3-layer plywood. These allowable F b stresses are for use in all-plywood beam design. They are not applicable to other uses. (b) Allowable stress in shear through the thickness (F v) shall be psi. When beams consist of two or. APA PRI APA Performance Rated I-joists (PRIs) are manufactured in accordance with PRI, Performance Standard for APA EWS I-joists, Form XThis Performance Standard provides an easy-to-use table of allowable spans for applications in residential floor construction, allowing designers and builders to select and use I-joists from various member manufacturers .

Strength of plywood-web box beam. This paper describes the loading tests carried out on box beams of two different lengths but of the same cross section. The overall sizes of the beams were mm X mm X m and mm X mm X m. The box beams were assembled by nailing plywood webs to both sides of timber without the use of adhesives.
