Type V engineered wood platform construction primarily uses engineered wood products in combination with what to bond structural connections?

• A. Nails
• B. Glue-laminated beams
• C. Mortise and tenon
• D. Adhesives

Answer: (D)

Engineered wood products gain their strength from bonding layers together with adhesives, and in Type V platform construction those adhesives are used to join members and transfer loads at connections. The adhesive bonds enable panels and laminated members to act as a single, continuous unit, which is essential for the integrity of the structure. While nails or other fasteners may be used to hold things in place, the key bonding method that ties the engineered pieces together is the adhesive. Glue-laminated beams are themselves formed by adhesives, not the bonding method for typical connections, and mortise and tenon represents traditional joinery rather than the modern bonded system.
