A method of reinforcing a structural element is disclosed. The method comprises positioning a first rigid fiber-reinforced shell extending between first and second edges partially about an external surface of the structural element to leave an exposed portion of the structural element. The method also comprises positioning a second rigid fiber-reinforced shell extending between first and second edges about the exposed portion of the structural element such the first edge of the second rigid fiber-reinforced shell adjacent the first edge of the first rigid fiber-reinforced shell to give a first seam and the second edge of the second rigid fiber-reinforced shell is adjacent the second edge of the first rigid fiber-reinforced shell to give a second seam. Finally, the method includes adhering the first and second rigid fiber-reinforced shells to the structural element. A reinforced structural element produced by the method is also disclosed.

The present disclosure is directed to climbing wall assemblies having a variety of improvements. For instance, the climbing wall assemblies may include connectors to attach the surface panels to the framework, in which the connectors may be mounted substantially anywhere along the front of the framework and at substantially any angle, providing for the securement of climbing panels in various geometries. The climbing wall assemblies may also include braces that may easily be adjusted to a desired length and configuration during construction of a climbing wall. The climbing wall assemblies may also include variable-angle, integral front posts, which provide for the easy and stable securement of climbing panels in various geometries. These improvements provide climbing wall assemblies that may be easily assembled to produce a desirable climbing wall structure having few framework components.

A one-piece structural fuse assembly is disclosed that is formed from a single piece of structural steel such as a beam. In embodiments, a first flange of the beam may form the fuse base, and a portion of the web of the beam may form the fuse plate. Additionally, a buckling restraint plate of the structural fuse assembly may be formed from a second flange of the beam, and the spacers of the structural fuse assembly may be formed from a portion of the web unused by the fuse plate. In examples, all of the components cut from the single piece of the beam are used in a single structural fuse assembly.

A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall. Each of a plurality of joist support brackets comprising an attachment portion configured to be attached to the web wall of the perimeter support member and a joist support portion. The joist support portion includes a pair of opposed lateral walls with each lateral wall configured to be attached to a corresponding lateral wall of a joist supported by the joist support wall.

A method of forming a post sleeve within a post hole in the ground to include a post receiving cavity to insertably receive and support a post is provided. The method includes positioning a post sleeve core within the post hole with the aid of an elongate installation member and depositing uncured material into the post hole to at least partially surround the post sleeve core while the post sleeve core is attached to the elongate installation member. The method further includes allowing the uncured material to harden around the post sleeve core to form at least a portion of the post-receiving cavity of the post sleeve and removing the post sleeve core from the hardened material to expose the post receiving cavity to receive and support the post. Other related methods of forming post sleeves are also provided.

A deformable device includes a deformable beam or hinge having an extended state, a flattened state, and a rolled state if a beam, where a stiffness and strength of the deformable beam or the hinge in the extended state is greater than a different stiffness and strength of the deformable beam or the hinge in the flattened state. A cross section includes a first about V shape half and a second about V shape half. Each half includes a vertex with at least one curve extending into two walls at least one of the walls including a plurality of truss members, both of the walls extend into a joining edge. The first about V shape half and the second about V shape half are joined together at a seam of a joining edge of the first about V shape half and the second about V shape half.

Systems, devices, and methods for precision boom deployment are provided in accordance with various embodiments. The tools and techniques provided may have space and/or terrestrial applications. Some embodiments include a boom deployment system that may include a furlable boom. Some embodiments include: boom reinforcement devices, end fitting devices, contoured support devices, edge support devices, spiral harness devices, latch devices, combined boom spool and tension drive devices, and/or rotary encoder devices. Some embodiments may utilize a composite slit-tube boom. Some embodiments utilize a furlable boom that may be fabricated with curvature along its length.

A mechanical utility invention that creates a self-leveling detachable base that when attached to the member beam of the parent application U.S. Ser. No. 15,703,993, creates utility in its substantially different shape, mobility, multi-functional capabilities, and sustainability from its conventional counter part. It can be utilized as a means for independent balance, manipulate angular degrees, attaching to a sub-surface, and attaching to additional member beams. Additionally, it can be used with the expandable sustainable platform from the parent application. Additional utilities include, but not limited to: creating an arch way, creating a plumb and post without the use of digging and concrete, creating a means for a work to attach a beam without the need to for additional workers to stabilize during attachment. Thereafter, it can be used lend to a member beam the ability to install and uninstall and used again for like or different utilities, making the base and the beam largely sustainable.

A crane, such as a bridge crane or gantry crane, having at least one horizontally extending crane girder, which is designed as a lattice girder having a plurality of braces and on which a crane trolley having a lifting device can be moved. At least some of the braces are planiform, and each of the planiform braces has a flat main surface, which extends transversely to a longitudinal direction of the crane girder. A first brace and a second brace form a brace pair and are arranged in an X-shape in relation to each other as viewed transversely to the longitudinal direction of the crane girder.
