Abstract: A breach detection system for a container includes at least two panels having a first electrical circuit mounted thereto. The panels are configured for attachment to a container. The first electrical circuit is configured to detect an intrusion through any portion of the panel and generate an intrusion signal when the intrusion occurs. A connector electrically connects the first electrical circuits of two panels of the container.

Abstract: A ballistic and blast protective composite panel includes a first composite layer and a second composite layer.

Abstract: A roofing panel assembly is made of a base and a cap as well as a plurality of I-joists having an upper flange, a lower flange and a web. The base is attached to the lower flanges of one or more of the plurality of I-joists and the cap is attached to the upper flanges of one or more of the plurality of I-joists.

Abstract: A panel having a central panel element formed of a composite material, having peripheral edges formed of a weldable material, such as steel. In one form, the panel element is rectangular, and the panel element on two of its opposite edges have a corrugated profile, while the other two of its opposite edges have a linear profile. Multiple panels may be joined together by welding at the peripheral edges, to form a secure container. The composite material of the panel element in some forms, includes intrusion sensors, for example including optical fiber pathways at electrically conductive pathways, as well as processors for effecting data transfer and analyses and secure communications. In some embodiments, the electrically conductive pathways include one or more bypass resistors to produce a different circuit resistance upon interruption of one or more of the pathways.

Abstract: An elongated sheet piling panel has a length and width, and opposed side edges, and has elongated voids positioned within the interior of the panel. The voids are oriented in the direction of the length of the panel, and the edges of the panel are configured to be connected to the edges of additional similar panels.

Abstract: A ballistic and blast protective composite panel includes a first composite layer and a second composite layer.

Abstract: A method of forming a laminated beam includes assembling a plurality of individual wood laminations in a juxtaposed relationship, and joining the assembled laminations together to form a laminated beam. The assembled laminations define a tension zone of individual wood laminations, a core zone of individual wood laminations, and an compression zone of individual wood laminations. The average thickness of the laminations in the tension zone is less than the average thickness of the laminations in the core zone, and the average thickness of the laminations in the compression zone is less than the average thickness of the laminations in the core zone.

Abstract: A wood sheathing panel, suitable for use in building construction, includes reinforcement strips of fiber reinforced polymer material incorporated into the panel. The reinforcement strips cover an area that is within the range of from about 5 to about 50 percent of the surface area of the panel. The reinforcement strips of fiber reinforced plastic material can be incorporated in the perimeter of the panel, or can be incorporated into the corners of the panel. The spacing of the intermittently incorporated reinforcement strips can generally coincide with a standard spacing of framing members so that when the wood sheathing panel is applied to a building frame, the reinforcement strips are generally aligned with framing members of the building. Preferably, the reinforcement strips are sufficient to provide an increased ductility over an equivalent unreinforced wood sheathing panel in an amount within the range of from about 75 percent to about 500 percent.

Abstract: A building construction configuration comprising an assemblage of wood sheathing panels positioned adjacent one another to form a panel assembly having elongated joints between adjacent panels, and reinforcement strips of fiber reinforced polymer material bonded to the panels. The reinforcement strips cover an area that is within the range of from about 5 to about 50 percent of the surface area of the panels. In another embodiment of the invention, there is provided a method of constructing a building comprising applying wood sheathing panels to a framework to form a building shell, bonding reinforcement strips of fiber reinforced polymer material to the wood sheathing panels to bond at least some of the wood sheathing panels to each other, and covering the building shell with a finished exterior.

Abstract: A Composite Structural Panel (CSP) includes a composite core that is preferably made of a plurality of vertically laminated Oriented Strand Board (OSB) sheets. The OSB sheets may be fastened together by using any conventional fastening means, such as an adhesive. Preferably, the CSP also includes a layer of polymer concrete applied to the top surface of the composite core, and a layer of glass fiber reinforced polymer (GFRP) reinforcement material having E-glass fibers applied to the bottom surface of the composite core. When the CSP is supported directly on the ground, the E-glass fibers of the GFRP reinforcement material are preferably oriented in a transverse direction with respect to the plurality of vertically laminated OSB sheets. A layer of protective material may be applied to the side surfaces of the composite core to provide additional protection from harsh environmental conditions.
