ABSTRACT:
Pre-cast concrete panels for use as deck components in a load supporting structure are constructed of non-metallic fibre reinforced concrete. Integral, transverse tension members are located externally adjacent the lower support surfaces of the panels and connected to the panels at their outer ends. The tension members carry compression forces applied to the panels by supporting an arching action, thereby avoiding the need to provide steel reinforcement across the entire interior of the concrete. This, in turn, reduces the risks of panel failure due to the corrosion of reinforcement steel located within the body of the concrete panel.
