connection yields

[cggage]

Would anyone know if there is a calculator, spreadsheet, or specifier that would determine the connection yields of plywood (or OSB) as a side member connector. Given information would be type of plywood and thickness as well as tensile forces and their angles, needed information would be whether or not the specified plywood could withstand the tensile forces being transferred through it. This would be as in the application of plywood as a gusset connector for wood trusses, connected by dowel type fasteners. It could be assumed that dowel type fasteners would not be a mode of failure in the application, but their inclusion to it could be helpful.

Thanks.

So you would like to check the plywood material in a gusset type application (not the connectors) if I'm understand correctly.

Take a look at APA Y510T (Plywood Design Spec) and/or APA D510 (Structural Panels). Maybe even APA H815 (design of all plywood beams) would be helpful.
The plywood and panel specs should give allowable shear and tension values. The semi-confusing part is correlating the thickness/APA rating and making sure you're specifying what you're designing. Another good article and example if your looking at a gusset type connection is:

Plywood connection yield modes are the same as other wood members. You need to know your SG value and any other modifiers as applicable. Get out the NDS to find all relevant information you requested. Additionally, dowel type fasteners would most certainly be the mode(s) of failure which needs to be considered.
