I know this is a bit dated thread but we just got from a local Glue-lam person a document that outlines using T&G decking for diaphragm shear action - provides 400 plf based on a particular connection scheme and a 3/8" bead of glue along the top of the tongues, forming a vertical glue joint between the top lams of the laminated decking.
The problem here is, that it is simply a brochure from a company that sells decking, and doesn't include any ICBO or ICC validation.
