A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

A series of moment frames, each including two opposing spaced apart vertical legs and a horizontal crossbar connecting the top ends of the legs, are arranged linearly in spaced apart side-by-side array and opposing outer horizontal panel support beams are connected to the outside faces of the legs on each building side, offset below the crossbars. On the inside faces of the legs and running parallel to the beams, first and second opposing crane rails are attached. A bridge crane is mounted on the crane rails. Four-panel folding sections are assembled in an adjacent side-by-side array and rest on the panel support beams. Individual wall panels, arranged side-by-side, enclose the space from the bottoms of the legs (ground level) to the panel support beams. End panels, in various configurations, close the ends of the crane building and allow access doors or and other openings.

Disclosed is a shelter having a base having base buses; a frame having curves and beams supporting the curves. Each end of the curves are attached to corresponding base bus; each curve is composed of curved elements, the curved element has means for connecting a curve to another curve with a beam. The shelter further has a cable, which cable is for tightening and supporting the frame. Additionally, there is a curved element, and a use of a shelter as a shelter for aircrafts or as a sports hall.

An adjustable lattice girder includes a first lattice girder portion having a first end and a second end positioned opposite the first end, with the first lattice girder portion having a first connection member, and a second lattice girder portion having a first end and a second end positioned opposite the first end, with the second lattice girder portion having a second connection member configured to engage the first connection member. The first connection member is slidable relative to the second connection member between a first position corresponding to a first distance between the second end of the first lattice girder portion and the first end of the second lattice girder portion, and a second position corresponding to a second distance between the second end of the first lattice girder portion and the first end of the second lattice girder portion. The first distance different than the second distance.

A frame truss made of two walls and a roof structure. Each of the two walls have an outer and inner chord. The outer and inner chords of each respective wall are not parallel, but the inner chords of the two walls are parallel to each other. The arrangement of the inner and outer chords of each wall creates an exterior overhang with respect to the ground. Each of the walls converge at their bases and are attached at their bases to a plate. The roof structure attaches to the top of each of the walls and spans between them creating a frame that can be assembled in conjunction with similar frames to construct a building system.

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 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.
