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.

Inflatable beam (1) comprising fire hoses or other industrial seamless hoses with woven textile braiding, inner air-tight lining and optional outer protective coating, is composed of an assembly of at least three hoses (2) arranged longitudinally side by side, where ends of the hose (2) are closed by a closure (3). At least one of the hoses (2) comprises at least one inlet and/or discharge member (4) for an inflating medium. The hoses (2) are at the point of contact of their circumferences, or at place of the closest distance of their circumferences mechanically connected by stiff connections (5) spaced along the length of the assembly of the hoses (2), at least one length (L) of at least one hose (2) between adjacent connections (5) of the hoses (2) is smaller than the length (M) of the other hoses (2) between these connections (5).

A pneumatic support having a body (112) which can be pneumatically pressurised and which, when under operating pressure, operationally holds a compression member (96, 128 to 131) which extends substantially over the length of the body and a tensile member (98, 138 to 141) which likewise extends substantially over the length (I) of the body at a distance from each other, wherein the compression member (96, 128 to 131) and the tensile member (98, 138 to 141) are connected to each other at the end in connection nodes (91), and wherein the body which can be pneumatically pressurised has pneumatic drop-stitch transverse fibre pressure panels (100, 165, 113 to 116).

The pneumatic support has a pneumatic body which can be placed pneumatically under pressure and which, under operating pressure, operationally keeps at a distance apart a compression member which extends substantially over its length and a tension member which likewise extends substantially over its length, wherein forces are introduced at force introduction points in end regions of the compression member and the tension member into said members and wherein connecting elements are provided between the compression member and the tension member and introduce forces into the compression member and the tension member likewise at force introduction points, wherein, furthermore, the pneumatic body has formations which extend between adjacent force introduction points and which project outwardly beyond a rectilinear connection between the adjacent force introduction points. As a result, undesired distortion of the support under operating pressure, but without operating load, is avoided.

A structural arch having one or more elongated tension members disposed within a shell or core at or near the lowermost edge of the arch, and one or more elongated compression members disposed within the shell or core at or near the uppermost edge of the shell. The core of the arch may be hollow, or optionally, lightweight filler material or filler members may occupy the core.
