A method for managing restoration assets, a restoration sensor, a system, and a controller for use in a mitigation environment are provided. An illustrative method may include receiving first sensor data describing an environmental condition in proximity to a first restoration asset, receiving second sensor data describing an environmental condition in proximity to a second restoration asset, comparing the first sensor data with the second sensor data, and determining a drying condition for a building in which the first restoration asset and the second restoration asset are provided based on the comparison of the first sensor data with the second sensor data.

The present disclosure is directed to an internal reinforcement assembly for a tower of a wind turbine. The reinforcement assembly includes a plurality of reinforcing rod members spaced circumferentially about the tower. Each of the plurality of reinforcing rod members includes a first end and a second end. The reinforcement assembly also includes an adjustable mounting component configured with each of the second ends of the plurality of reinforcing rod members. As such, the adjustable mounting components are mounted to an interior wall of the tower at a location to be reinforced. Thus, the reinforcing rod members interact with the tower to reinforce the tower at the location to be reinforced.

A concrete product comprising an adaptive prestressing system includes a concrete body and a composite wire embedded within the concrete body at a predetermined location. The composite wire comprises anchored end portions, each of which comprises a bonded wire segment constrained within the concrete body to resist axial motion, and an activable central portion between the end portions. The activable central portion comprises a shape memory alloy (SMA) wire segment and is axially movable within the concrete body. When heated at or above an austenite transformation temperature, the SMA wire segment contracts and the activable central portion exerts a tensile force on the end portions, thereby applying a compressive prestress within the concrete body at the predetermined location.

A connection element (12) of composite material includes a bundle of fibers (14) and a binding agent. The connection element (12) further includes an insertion portion (16) having two ends (18, 20). The insertion portion (16) includes a section of the bundle of fibers embedded in the binding agent to form a monolithic structure; at at least one of the ends (18, 20) a fixing portion (22, 24) is provided. The fixing portion (22, 24) includes fibers (14) overhanging from the insertion portion (16) and partially embedded in the monolithic structure. The fibers are predisposed with anchors (26, 28) adapted to form an anchorage between the fibers (14) of the fixing portion (22, 24) and a plaster and/or a reinforcement element.

A method to strengthen or repair concrete and other structures comprises securing a plate having a shape memory alloy (SMA) wire embedded therein to a localized region of a structure. The SMA wire has a deformed shape configured for self-anchorage within the plate. The SMA wire is heated at or above an austenite transformation temperature, and the SMA wire resists shape recovery and remains self-anchored within the plate. Accordingly, a compressive force is generated within the SMA wire and transferred to the plate. At an interface between the plate and the localized region of the structure, the compressive force is transmitted from the plate to the structure, thereby providing localized prestressing of the structure.

A method for reinforcing a concrete structure so as to have high substrate visibility and sufficient reinforcing performance. A fiber sheet for reinforcing a concrete structure, the sheet including: a framework in which a filament-based, multi-axial mesh sheet and a matrix resin are integrated, wherein the multi-axial mesh sheet has a base weight amount in a range of 500 g/m.sup.2 to 1000 g/m.sup.2.

A fracture caused by fatigue of a connecting portion positioned at a corner of a reinforcing frame directly secured to a frame is avoided regardless of a relative displacement that occurs in the frame upon disposing the reinforcing frame made of steel, which has an elevational shape surrounding the frame along an inner circumferential surface of the frame and a cross-sectional shape with a flange on a side of the frame, in a structure plane of the frame of a column and a beam of reinforced concrete structure, and joining the reinforcing frame to the inner circumferential surface of the frame. A reinforcing frame is constituted of a column portion along a column of a frame, a beam portion along a beam, and a connecting portion that is joined to the column portion and the beam portion, and connects the column portion to the beam portion. The connecting portion has a flange with a part close to the column portion and the beam portion formed to be shaped along an inner circumferential surface of the frame, and a part of the flange facing a corner of the frame formed into a shape in which a void is formed between the part and the corner of the frame.

An anti-seismic performance reinforcement structure of a masonry structure and a construction method of the same are proposed, where a deformed bar is constructed to be tied to the entire circumference of the masonry structure at every predetermined height thereof such that the masonry structure is connected to a wall, thereby simplifying a construction process, and inducing the masonry structure and the wall to be moved integrally to each other during an earthquake so as to prevent the masonry wall from collapsing. The method of performing anti-seismic performance reinforcement and crack repair of the masonry structure includes: removing a predetermined depth of a horizontal joint; mounting the cross joint by forcibly press-fitting the cross joint having the press-in holder and the horizontal holder to a perforated position; fixing a deformed bar fixture to the wall; and tying the entire circumference of the masonry structure with the deformed bar.

A self-stressing shape memory alloy (SMA)/fiber reinforced polymer (FRP) composite patch is disclosed that can be used to repair cracked steel members or other civil infrastructures. Prestressed carbon FRP (CFRP) patches have emerged as a promising alternative to traditional methods of repair. However, prestressing these patches typically requires heavy and complex fixtures, which is impractical in many applications. This disclosure describes a new approach in which the prestressing force is applied by restraining the shape memory effect of nickel titanium niobium alloy (NiTiNb) SMA wires. The wires are subsequently embedded in an FRP overlay patch. This method overcomes the practical challenges associated with conventional prestressing.

Methods are provided for repairing an existing structure to cover at least a portion of the existing structure with a repair structure. Such methods comprise mounting one or more standoff retainers to the existing structure; coupling one or more standoffs to the standoff retainers such that the standoffs extend away from the existing structure; coupling one or more cladding panels to the standoffs such that the panels are spaced apart from the structure to provide a space therebetween; and introducing a curable material to the space between the panels and the existing structure, the panels acting as at least a portion of a formwork for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the panels. Corresponding apparatus for effecting such methods are also provided.
