Title: Ferrocement Steel-Plate Composite Beams

Abstract:Fourty beams were tested in flexure to determine the behavior of composite beams constructed with 1 in. (2.54 cm) thick ferrocement and 1/4 in. (0.635 cm) thick steel plate sections and that of beams made with 1 in. (2.54 cm) thick reinforced concrete and 1/4 in. (0.635 cm) thick wall plate sections. Epoxy and shear studs as well as natural bond were used to transfer shear between the plate and the concrete. Ferrocement composite beams were twice as strong but less ductile than reinforced concrete composite beams. A sandblasted steels surface plus epoxy provide adaquate shear transfer, although shear studs allowed the greatest ductility. In general, calculated ultimate loads conservatively predicted beam failure.
