Deck Lateral Load – The Truth Revealed
The lateral load anchor provisions that came into the 2009 IRC have had a dramatic affect on the decking industry.
Born from a fear of band joists being ripped from homes by the decks they support, a best guess to bypass the band joist altogether came into the code. Though only “permitted” it is often required.
New testing from Washington State University dismantles the fear and shows the strength of a lag-screw connected ledger…without the extra metal.
NADRA has been diligently representing and supporting the decking industry in the code development process. Now, in 2013, the 2015 IRC is being created, and NADRA took the opportunity to get these research results included in the discussion. NADRA’s work can be reviewed HERE
