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.

A structural member for a building, the structural member comprising: at least two spaced apart sidewalls, each sidewall formed from at least one contoured metal sheet; and at least one connecting vertex through which the sidewalls are connected, each connecting vertex include at least one structural bend formed in at least one of the contoured metal sheets, the sidewalls being connected through the connecting vertex to form a structural span therebetween, wherein each structural bend is formed between a first sheet section and a second sheet section of the respective contoured metal sheet, the first sheet section and second sheet section being connected about a bend line with the first sheet section extending from the bend line at a selected angle relative to the second sheet section, and wherein the first sheet section has a contoured profile that is a symmetrical mirror of the contoured profile to the second sheet section about the bend line.

Disclosed herein is an apparatus for a building frame designed to create a building, in accordance with some embodiments. Accordingly, the apparatus may include a plurality of base plates. Further, the apparatus may include a plurality of top plates. Further, the apparatus may include a plurality of studs. Further, each stud of the plurality of studs may include an elongated stud body having an upper stud end and a lower stud end. Further, the apparatus may include a plurality of rafters. Further, each rafter of the plurality of rafters may include a first slab body. Further, the each rafter may include a first cuboidal body. Further, the apparatus may include a plurality of braces corresponding to a plurality of brace lengths.

A moment frame is disclosed for a sloped roof construction. The moment frame includes a lateral bracing system having a high initial stiffness and including yield links capable of effectively dissipating energy generated within the lateral bracing system under lateral loads.

A modular perimeter frame system is described for forming a perimeter frame used in the construction of floors, walls and roofs of buildings. The modular perimeter frame system has a first modular sub-frame having one or two blunt end portions, and a second modular sub-frame having one or two overhang end portions. The blunt and overhang end portions are so dimensioned and shaped as to facilitate a continuous abutting engagement between at least two surfaces which meet at a corner of the blunt end portion and at least two surfaces which meet at a corner of the overhang end portion.

A composite building system comprising a structural frame and walls which is made of pultrusion fiber reinforced polymer (PFRP) material. PFRP provides increased performance, strength, protection, and longevity for mobile and fixed building structures, enclosures or vehicles, commonly found in residential, commercial, industrial, healthcare, aerospace, government defense, energy, and agriculture sectors. The PFRP material comprises fibers embedded in a resin matrix. Exemplary fibers are glass, carbon, and synthetic fibers. PFRP products can be formed using a pultrusion method that eliminates outgassing. An intumescent fire barrier can be applied to the PFRP to meet National Fire Protection Association fire endurance codes and standards. The composite building system increases personal safety while reducing weight, labor costs, construction time, and total cost of ownership over the life of the structure while being resistant to ballistic, seismic, corrosion, rotting, impact, and insect damage. In addition, a wall and wall assembly consisting of the PFRP material is impervious to water and air and does not require an exterior finish coating. The PFRP wall and wall assembly can be designed to be versatile, allowing for use with both PFRP structural framing and traditional framing materials, such as concrete, steel, and wood.

Wall systems and buildings having such wall systems are disclosed. Such wall systems include parametric mullions each of which is constructed from a plurality of interconnecting components so that the wall systems may be disposed much closer to the building frame than conventional wall systems. Such wall systems may include panels disposed to form convex or concave facades. Such wall systems may also include decorative features superimposed over one or more panels or extending outward from the facade surface. The parametric mullions may be formed into trusses which may be used as part of a wall system or independently of such wall systems.

A method including placing on a surface a first beam having a first end with a first clevis component opposing a second clevis component. A second beam, including a second end having a third clevis component opposing a fourth clevis component, is placed adjacent the first end on the surface. The first clevis component is connected to the third clevis component. A lifter is connected to the first end and the second end, which are lifted simultaneously from the surface while rotating the first beam and the second beam about the connector until the second clevis component engages the fourth clevis component. Connection between the second clevis component and the fourth clevis component then may be completed.
