Abstract: A load supporting structure such as a bridge deck is mounted on two spaced beams and includes a pre-cast concrete panel with a plurality of transverse tension straps attached to the edges of the panel by anchoring studs attached to the tension member and embedded within the panel such the tension straps—prevent spreading of the panel so that loads are transferred from an upper surface of the panel to the beams by forming a compressive arch within the panel. A concrete deck slab is cast over the pre-cast panel and is attached to the tension straps by embedded anchor studs located on the straps outside the panel so as to form a compressive arch within the slab. The compressive arch loading avoids the use of tension reinforcing steel in the concrete which can corrode. The use of a pre-cast panel and cast slab simplifies assembly as no welding to the beams on site is required.

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.

Abstract: A load supporting structure includes a pair of beams with tension members extending between them. A deck formed from fiber reinforced concrete is supported on the beams with fasteners extending between the beams and deck. The tension members provide sufficient rigidity to allow an arching action to develop within the deck and thereby avoid the need for steel reinforcements within the deck.
