ABSTRACT
ABSTRACT: This paper deals with a steel-concrete composite bridge deck with perfobond rib shear connectors. The proposed deck system is composed of profiled steel sheeting, perfobond ribs, steel reinforcements, and concrete. Figure 1 shows a schematic of the composite bridge deck system proposed in this study. The deck consists of profiled steel sheeting, perfobond rib shear connectors, steel reinforcements, and concrete. The perfobond rib acts as a shear connector and as a longitudinal stiffener within the profiled sheeting. The perfobond rib shear connector consists of a steel plate with a number of uniformly spaced holes. If the holes in the perfobond rib are filled with concrete, concrete dowels are formed, which provide horizontal shear resistance between the steel and the concrete.
