Abstract: A roof system includes a roof panel formed of concrete and an architectural surface such as a corrugated surface. A first layer of reinforcing material is disposed along and spaced inwardly from a first surface of the roof panel, and an optional second layer of reinforcing material is disposed along and spaced inwardly from a second surface of the roof panel. The first layer of reinforcing material is spaced from the second layer of reinforcing material. The reinforcing material may be formed of fiber-reinforced polymer mesh, made with carbon fibers or glass fibers. FRP rebar may be used in conjunction with FRP mesh to provide added structural strength. The roof panel may include one or more elongated ribs having a thickness greater than adjacent portions of the roof panel. In other aspects, concrete structures with reinforcing material may be used for either roof panels or wall applications.

Abstract: Fiber reinforced plastic FRP formed about concrete piles and columns. The FRP components generally includes an exterior shell and an interior protruding portions. The concrete filled FRP tubes are enhanced by prestressing the concrete core, thereby increasing the bond with the tube and placing the tube in an active hoop tension. The prestressing can be developed by either post-tensioning a series of strands(or tendons) that are placed inside the core, or by using expansive core materials which do expand upon curing and will therefore impose an active pressure on the confining tube. The bond can be developed by either internal resin grids, FRP spirals, FRP orthotropic grids, sand-resin coating, bonding agent or protruded ribs. The system can be used as a fender pile, bearing pile, bridge pier column, or any structural column. The system can be made by pultrusion, SCRIMP, REM, centrifugal methods or hand lay-up.

Abstract: Fiber reinforced plastic FRP formed about concrete piles and columns. The FRP components generally includes an exterior shell and an interior pultruted component. The exterior shell can include multilayers of fibers wrapped in straight hoop patterns in single sheets with or without longitudinal axial fibers. Alternatively the exterior shell can include angled wrapped fibers. The interior FRP pultruted component comes in various forms such as pultruted ribs, crossed attached ribs, interior co-axial concentric cylinders and additional shapes such as ones having an H cross-shaped pattern. The FRP materials can consist of fiber and resin such as a preferred embodiment of approximately 60% glass and 40% polyester. Other fiber type materials include but are not limited to glass, carbon, Kevlar, combinations thereof, and the like. Types of resin include but are not limited to polyester, vinylester, epoxy, combinations thereof, and the like.
