Composite wall panels are a viable method of quick and inexpensive building. Providing a composite wall panel with increased shear resistance and axial load capacity is extremely desirable. A fiber reinforced polymer (FRP) cage incorporated into composite wall panels which forms a wall panel with these desirable characteristics and a method of forming such a composite wall panel is disclosed and described. The FRP cages can include FRP shells or sleeves which include two or more bars secured thereto. One or more FRP cages can be incorporated into a composite wall panel where a portion of the FRP shell is imbedded in each of two concrete layers with an insulation layer therebetween. The resulting FRP reinforced composite wall panel has improved shear resistance and axial compressive strength which can allow for use in load bearing applications and generally improved properties such as thermal insulation.

Strengthening reinforced concrete columns by using Fiber Reinforced Polymer (FRP) composites can be an effective method of retrofitting existing columns. FRP composites have a number of advantages over steel, including their high strength-to-weight ratio and excellent durability. The confinement effectiveness of FRP materials for rectangular sections can be improved by performing shape modification such that a rectangular column section is modified into a shape that does not have 90 degree comers such as an elliptical, oval or circular column. An expansive concrete can be advantageously used between the FRP material and the existing concrete in order to post-tension the FRP material circumferentially and improve confinement of the concrete. A finite element analytical model is also disclosed which model describes the stress-strain relationship for the FRP-confined columns after shape modification.

Anchoring devices and systems are disclosed for use with elongated reinforcement members such as FRP, SRP, metallic bars, or cables. Such devices and systems impart a compressive stress into a static structure having the elongated reinforcement member running therethrough or therealong. An anchoring system can include an anchor block that includes a front end surface for contacting the static structure, an axial bore for receiving the elongated reinforcement member, and clamping members that, when closed, exert a radial clamping force on a reinforcement member in the axial bore. A tensioning and anchoring system may include one or more tensioners integrally connected to an anchor block. At least one sleeve may be secured to the anchor block and cooperate with a bolt that displaces the anchor block to place a tensile force on the elongated reinforcement member and impart a compressive force on the static structure.

Cementitious building panels are connected together using a connector plate made of a composite material of carbon fibers embedded in an organic matrix. The interconnection is made by removing cementitious material to form recesses in the building panels, applying an adhesive material into the recesses prior to placing the connector plate into the recesses, and thereafter affixing the connector plate to the first-panel face and to the second-panel face in the recesses and extending across the gap between the first-panel edge and the second-panel edge.

Exemplary sheet and rod attachment apparatus and systems are described for providing composite reinforcement for one or more structures, such that one or more structures can be supported by different reinforcement mechanisms. The sheet and rod attachment apparatus includes an adaptor that couples the sheet to the rod in a manner that minimizes or substantially eliminates localized stress concentrations. The adaptor may include one or more wedge-shaped bodies contoured and configured to attach to at least a portion of a rod of a predetermined size and/or shape. A wedge-shaped body may include an interior surface for engaging the rod, and exterior surfaces extending radially from the interior surface. Example exterior surfaces are configured to engage a reinforcement sheet that extends axially from the rod.
