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.

The present invention relates to methods for reclaiming plastics and cellulose materials for use in a variety of applications, including as alternative fuel sources. According to one embodiment of the invention, waste is received which includes cellulose materials and plastics. Such materials are sorted from other materials and the cellulose and plastic materials are shredded or ground and then blended together. The blended materials can then be fed to an energy converter, such as a combustion unit or a gasifier, where they are burned as fuel source or used to create synthetic gas. In other embodiments, the blended materials are heated or have a binding element added thereto. Such mixture is then compressed to form a desired shape or sized object, and that object can then be packaged, distributed or used. The blended object can be used as a fuel source, or as a building, sound attenuation, or insulation material.

A system and method are provided for removal of undesirable substances from a body of liquid. The system can include an aeration structure having a continuously inclined surface configured to provide an interaction of air bubbles against substantially an entire length of the continuously inclined surface while the air bubbles are moving toward a top of the body of liquid. The continuously inclined surface can be substantially submerged in the body of liquid. A bio-film of diverse bacteria colonies is disposed on the continuously inclined surface, and a high surface area-to-volume structure is located in proximity to the aeration structure, upon which a bio-film of bacteria colonies can be formed. An aeration system is coupled to an air supply system which releases the air bubbles toward a bottom of the continuously inclined surface, such that the air bubbles move along the continuously inclined surface as they rise so as to (i) create a variety of aerobic-anaerobic conditions at the bio-film and (ii) engage the air bubbles in a continuous mixing of a micro climate for the bio-film in response to an orientation of the continuously inclined surface and (iii) provide airlift circulation of water from bottom to top of the aeration structure.

Residual tensile stresses can be mitigated through methods and systems provided by the present invention. Such a method can include securing a metal member () to a substrate and at least partially surrounding a portion of the metal member () with a cooling fluid (). As a result, the cooled portion of the metal member () contracts a predetermined amount. Once cooled, the metal member may be fixed, preferably welded, to another metal member in a constrained relationship. As the portion of the metal member is returned to its original temperature, expansion of the metal member acts to mitigate residual tensile stresses in the metal assembly. Tensile stress in restrained members, cambering, and structural deformation can be readily controlled in an assembled structure.

Disclosed are apparatus and systems for absorbing seismic energy through non-linear yielding as a structure experiences lateral displacement. A seismic damper according to embodiments of the present invention includes at least one flat plate which can be perforated to include a plurality of apertures and/or cut-outs. One or more interior apertures are formed in the plate, and cut-outs may be formed along outer edges. External nodes are defined between the apertures and the cut-outs and stresses focus on the nodes to reduce non-linear displacement of a brace system to which the seismic damper is attached. One or more tension straps can be attached to the flat plate. Tension straps can be rotated relative to each other. Multiple tension straps may also be on the same surface. Multiple tension straps on the same surface may be nested and parallel.

A system and method for reducing the content of ammonia in water provides a submerged surface having a growth of nitrifying bacteria thereon. An aeration system creates air bubbles that travel along the surface as they rise to create aerobic conditions on the surface, and to circulate the water along the surface to allow the nitrifying bacteria to remove ammonia from the water.

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.

The present invention relates to apparatus and systems for absorbing seismic energy to prevent non-linear displacement in a structure. A seismic damper according to embodiments of the present invention includes at least one flat plate which can be perforated to include a plurality of apertures and/or cut-outs. Interior apertures are formed in the flat plate, and one or more cut-outs along outer edges. Nodes are defined between the apertures and the cut-outs and stresses from transferred energy focus on the nodes to reduce non-linear displacement of a brace system to which the seismic damper is attached. One or more tension straps can be attached to the flat plate. The interior apertures may include a single aperture, or multiple apertures. The apertures may include slots. Two plates may be connected and rotated relative to each other placing the apertures out of alignment.
