APPLICATION OF PREFABRICATED HOLLOW STEEL DECKS TO BRIDGE CONSTRUCTIONS

At the 10th Congress of International Association for Bridge and Structural Engineering in Tokyo, in 1976, the authors introduced a prefabricated hollow steel deck as a floor system for long-span suspension bridges. In this paper, they are proposing the application of this new deck to the main structure of smaller bridges. This deck has been used in bridges and floor systems in Japan. Here, the authors discuss the structural features and fabrication of this deck and present examples of its application to bridge construction. They also discuss the problems of design and construction of bridges using this deck, the methods of solving these problems, and the experimental studies conducted on the deck. This hollow steel deck is a prefabricated slab structure made up of two face plates with evenly-spaced core plates arranged diagonally between them. Tests have shown that this deck improves a bridge's lateral and torsional rigidity as well as its shearing resistance and fatigue strength. In that this deck is a prefabricated structure, its application facilitates bridge construction. Furthermore, the total thickness of the bridge structure can be reduced, thus improving its aesthetic appearance. /Author/
