A magnetic strut channel fitting (10) includes first and second plates (12, 14) connected to each other and a plurality of magnets (16) embedded into at least one of the first and second plates. According to another embodiment of the present invention, a magnetic strut channel fitting includes a substantially flat plate and a plurality of magnets embedded into the plate. According to yet another embodiment of the present invention, a magnetic strut channel fitting includes a substantially flat connecting plate, first and second arm members, each of the first and second arm members having a vertical plate and a horizontal plate, and a plurality of magnets, the plurality of magnets embedded into the connecting plate to allow the magnetic strut channel fitting to be magnetically adhere to a strut channel. The plurality of magnets allow the magnetic strut channel fitting to be magnetically adhered to a strut channel.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

An assembly for integrating an elongate structural member is provided. The elongate structural member includes a first end portion, a second end portion, and an elongate mid-portion that extends between the first and the second end portions. The first end portion is within a first plane and the second end portion within a second plane, and the first and the second planes are offset and parallel to each other. The elongate mid-portion is sloped between the first and the second planes. each of the first and the second end portions defining therein a polygonal hole. Multiple elongate structural members may be used to assemble a lattice structure.

A structural frame for a building, comprising: adjacent first and second columns; at least one precast concrete floor slab having first and second corner indents located in two adjacent corners and a first elongated edge beam defined between the first and second corner indents, the first elongated edge beam being disposed between the first and second columns such that the first and second columns are received in the first and second corner indents and that the first elongated edge beam abuts the first and second columns; and a first tendon assembly extending between the first and second columns and adapted to be tensioned to compress the first elongated edge beam between the first and second columns, the first tendon assembly including at least one left cable and at least one right cable located symmetrically on either sides of a vertical center plane of the first and second columns.

A sandwich structure includes two face plates, with a lattice structure between the plates, and with hard points at selected locations. The face plates, and the lattice structure with its hard points, may all be made as a single continuous piece by an additive manufacturing process. The hard points may be strengthened and/or stiffened areas of the lattice that may be used for connecting fasteners, or for other purposes. The hard points may be located at the junction between the lattice and one of the faces, and may be a locally thickened portion on one of the faces, for example being a cylindrical or parallelepiped protrusion out from the face. The hard points may serve the purpose of a built-in nut plate, such as themselves containing threaded holes, or by having a threaded inserts put into holes or recesses in the hard points.

In one aspect, a smart corner is provided that can be prefabricated. The smart corner comprises a rear side including a first hole, a first side including a second hole, a second side including a third hole, and a top. A wall frame is also provided. The wall frame includes a top plate, a bottom plate, studs, and four smart corners. A framing system is also provided comprising at least two wall frames. The at least two wall frames connect via the smart corners.

A connector assembly, having an upper connector coupled to a lower connector and a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly.

A method of making a virgin joint between at least two separate structural hollow sections in a truss or jacket structure made of the at least two structural hollow sections may include the steps of applying a fiber reinforced polymer wrap around the at least two structural hollow sections in a transitional area, covering and thus bonding together the at least two structural hollow sections, and forming the virgin joint between the at least two structural hollow sections and the fiber reinforced polymer wrap. Welding of the virgin joint between the at least two structural hollow sections is avoided.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.
