A deterioration of typical reinforced concrete bridge deck is due to the use of calcium chloride, cracks and water penetration inside of the deck slab with steel reinforcement. Therefore, in order to eliminate the defects of reinforced-concrete decks in terms of material, the steel-straped deck system is studied and developed by maximizing the arching effect while the girders are restrained using straps in lateral direction to the bridge. This parametric study was performed to analyze the structural characteristics of steel-straped deck, and to identify the factors of the thickness, span length and lateral restraint stiffness of deck slab considering the concrete nonlinearity.
