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.

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).

Embodiments of the present disclosure relate to a structure that comprises at least one layer of air beams that define an interior space of the structure wherein laterally adjacent air beams are configured to laterally abut each other. Optionally the structure comprises at least a first layer of a plurality of air beams and a second layer of a second plurality of air beams, wherein the second layer is positioned adjacent to and interior to the first layer for defining an interior space of the protective structure. A structure with laterally abutting air beams may better protect the occupants and contents within the structure from the effects of an explosion. Constructing a structure with at least two layers of air beams may provide a stiffer structure as compared to a structure that is constructed from a single layer of air beams.

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.

The present invention provides a modular system for constructing a structure assembly. The system comprises first and second sidewall components each comprising a set of spaced-apart longitudinally oriented grooves disposed in a first face thereof. The system comprises a plurality of rib components, each rib component having a pair of elongated protrusions extending from opposing sides of the rib component and, each protrusion being shaped to matingly engage with at least the first portion of the groove to connect the first and second sidewall components along a face-to-face direction. The system further comprises two elongate key joint members matingly engaging with two respective additional sidewall components to connect the sidewall components with the additional sidewall components along a transverse direction perpendicular to the face-to-face direction in a side to side relationship.
