A quonset style building is provided with an arched-roof defining a width, length and height, and tower supporting the roof adjacent its apex. The tower separates storage areas on opposite sides of the building. The tower also permits the building height and width to be increased over conventional quonset buildings, and allows the width to be 3× the height, while withstanding typical weather forces, including wind and snow.

Method of manufacturing a dome comprising: providing a plurality of components; joining a first and a second component together, joining the first and second components together comprising: positioning the first component and the second component in an initial position in which the first surfaces of components are angled from each other by a first angle; melting a volume of material extending between the first and the second component, the volume of material increasing in thickness from the second surfaces to the first surfaces; and the volume of material cooling and solidifying so as to join the first component and the second component together, the cooling of the volume of material reducing the angle between the first surfaces to a second angle less than the first angle such that the first surfaces face towards a centre of the dome and the first and second components form part of the dome.

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.

Arch structure defining equidistant points along a radial curve and comprising uniformly-sized, standard stock, elongated rectangular cross-section stringer members, uniformly-sized, standard stock, elongated rectangular cross-section arch members each having a midpoint and first and second angled ends of equal but opposing to one another angular magnitude, each arch member adapted to converge crossways on and completely abut a side surface of two non-adjacently positioned stringer members, each of the arch members further being adapted for undergirding a stringer member located between two non-adjacently positioned stringer members at the mid-point of the arch member, each arch member adapted for being oriented in scissor-like crossing relationship to another arch member, a plurality of fasteners, and where needed at least one tensioning member preferably attached between end stringer members, or alternatively between foundation members, the tensioning members and fasteners making the arch structure fortified to be as if monolithic.

A one-piece truss adapter for supporting single-axis trackers with truss foundations. A y-shaped structure has a pair of legs with an angularly adjustable connector for securely joining the one-piece adapter to a pair of driven screw anchors at different angular orientations. Each leg terminates in a ball-shaped connector that is received in a socket integral to a driving coupler at the head of each screw anchor. A retaining nut holds the connector in place to complete the angularly adjustable assembly.

The disclosure is directed to an elongated geodesic dome with an arched-tunnel section. In some embodiments including: a first adjustable angle hub connector, the first adjustable angle hub connector being a connector of a first plurality of tubular struts, the first plurality of tubular struts being inserted into the first adjustable angle hub connector; a second adjustable angle hub connector, the second adjustable angle hub connector being a connector of a second plurality of tubular struts, the second plurality of tubular struts being inserted into the second adjustable angle hub connector; a third adjustable angle hub connector, the third adjustable angle hub connector being a connector of a third plurality of tubular struts, the third plurality of tubular struts being inserted into the third adjustable angle hub connector. The adjustable angle hub connectors may be removable for adjusting a length of the arched-tunnel section of the elongated geodesic dome.

Arch structure of steel frame construction comprising: a plurality of elongated metal or steel stringer members and arch members, each stringer member and arch member comprising one of a tubular, I-beam, I-beam angled flange, C-beam, T-beam, and L-beam, cross-section shape, each of the plurality of arch members undergirding a one of the plurality of stringer members located between two non-adjacently positioned stringer members at a mid-point of each of the plurality of arch members, each of the plurality of arch members being oriented in crossing relationship to another of the arch members, the arch members being oriented for indirect complete abutting, and without any notch in any the arch member or any the stringer member, side surfaces of the plurality of stringer members via a plurality of brackets and fasteners. Or, the arch member ends may completely abut and be welded to side surfaces of the stringer members.
