An adjustable structural connectiona connection which can be adjusted to alter the location and angle of member attachmenttransforms the traditional notion of connections as a static means of connecting members at specific angles to a dynamic means of assembling a variety of structurally efficient forms. The adjustable connection connects a diagonal member to a vertical or horizontal member using either curved plate mounted to both of the structural members or a temporarily rotatable link. The adjustable connection can be used in a kit-of-parts type system, using multiple versions of the adjustable connection, which can join members at a wide variety of angles using a small number of unique components.

The pneumatic support according to the invention has pneumatic bodies 61 to 63 which can be placed under pressure and which operationally keep a compression member 51 and a tension member 52 at a distance apart, resulting in a pneumatic support with high loadability but also, disadvantageously, with high operating deformation. The connection elements 57, 58 extending in a zigzag shape between the compression member 51 and the tension member 52 over the length of the support 50 are preferably diagonal struts formed as flexible tension members and reinforce the support 50 with respect to the pneumatic supports of the prior art in such a way that the deformation of said support in the case of an asymmetrical load, as is the case with a bridge over which vehicles travel, is for example still 10%.

This disclosure presents a new strategy for modular construction: an adjustable module. This disclosure develops a new adjustable module comprised of a four-bar linkage which can form more efficient variable depth structures. Applications can include rapidly erectable bridges, roofs, buildings, and grid shells, among others. This disclosure provides specific detail related to rapidly erectable bridge applications for variable depth arch forms. Existing rapidly erectable, steel panelized bridge systems have limited material efficiency as they are comprised of rigid modules in a girder-type configuration. This disclosure shows that the module can form variable depth three- and two-hinged arches which increase the material efficiency. The module and other arch components can be made of standard rolled steel sections, thereby forming a versatile, kit-of-parts systems.
