Deck and balcony collapses injure occupants every year. It is estimated that over 40 million decks in the US are more than 20 years old, meaning they were constructed before today’s building codes and established best practices. To encourage compliant deck design and construction, American Wood Council (AWC) has published Design for Code Acceptance No. 6 – Prescriptive Residential Wood Deck Construction Guide (DCA 6) which may be downloaded from the AWC website here http://awc.org/codes-standards/publications/dca6 Requirements of the 2012 International Residential Code and other provisions are reflected in this document. This article highlights certain engineering topics related to DCA 6 and provides some background for those issues.
