LEESBURG, VA. – The American Wood Council (AWC) has released an update to “Design for Code Acceptance (DCA) 3 - Fire-Resistance-Rated Wood Floor and Wall Assemblies.”
The updated DCA 3 can be found on the AWC website: http://www.awc.org/codes-standards/publications/dca3.
“Wood-frame assemblies are common for many reasons, including ease of use, affordability, low environmental impact and energy-saving performance. This guide further increases the ease of use by laying out the fire-resistance-ratings of a variety of wood-frame wall, floor and ceiling assemblies,” said AWC Manager of Engineering Technology Jason Smart, P.E.
The primary update to the guide is the addition of exterior wall-floor intersection details in Type III construction. Example details have been included for Type III-A and Type III-B platform construction.
