Abstract: This paper briefly discusses the historical development of composite steel grid decks. The static and fatigue behavior under bending of filled and unfilled steel grid decks (exodermic) are discussed. The strength and stiffness of filled and unfilled (exodermic) composite steel grid decks in the pre- and post-yielding range are also discussed. Emphasis is given to understanding the internal and external actions of composite decks and establishing composite moments of inertia, along with the strength and stiffness characteristics of the above decks.
