The APA (American Plywood Association) provides reference design values for structural glued laminated timber (glulam) by principles initially established by the U.S. Forest Products Laboratory. These values are integral for the design of structural glulam members.

Glulam is a stress-rated engineered wood beam composed of wood laminations, or “lams,” bonded with durable, moisture-resistant adhesives. The grain of the laminations runs parallel with the length of the member. Glulam is versatile, ranging from straight beams to complex, curved members.

The American Institute of Timber Construction (AITC) and APA–The Engineered Wood Association (APA) developed and published the reference design values. These values are used by the National Design Specification®(NDS®) for Wood construction.

You can visit the relevant resources directly for more specific information or to view these reference design values.
