Whether the deck framing is free-standing or attached to a structure with a ledger board, joists span the distance and help shape a deck. 4. I can not fine a code requiring "bridging", at center areas. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. "The blocking or bridging between joists (or rafters) also contributes to this phenomenon. Our code report (ICC ESR-1153) specifically states that bridging is not required for floor and roof TJI joist applications. (Quick reference chart at the bottom of this document) 2.
