• Abstract:
  The research described here has resulted in the development of a simplistic and innovative interlocking ; glulam bridge deck panel for use in temporary bridge deck applications. The key feature of this panel ; system is the interlocking tongue and groove joint. The joint provides both displacement compatibility ; and structural load transfer between panels. The unique structural tongue and groove design ; successfully addresses two common issues with existing transverse glulam bridge decks: ; 1. It reduces differential movement between panels which is a very common problem with ; noninterconnected glulam deck systems in use today. ; 2. It allows the deck system to be installed completely from the top, eliminating the need for ; workers to install bolts from underneath the bridge deck. ; Other design advantages of the panels include: prefabrication for rapid on site installation, reusability, ; and because they are made from wood, the panels are relatively lightweight and have a relatively high ; strength to weight ratio when compared to steel and concrete alternatives.
