The Geometrica System of Construction
Frame structures and domes can be used in a variety of venues that necessitate large expanses of space. Arenas, atria, museums, houses of worship, and industrial buildings such as factories, plants or bulk storage for cement, and the power and mining industries, require large covered areas without intermediate support columns. In order to realize these large structures effectively, expert design professionals must shape these buildings to take advantage of form as a structural element.
The Geometrica System
Geometry, and the building system used to realize it, are clearly interrelated. Unless the right combination of structural system and overall geometry are used, the resulting structures may not be feasible. Geometrica overcomes these challenges with a trademarked system that is showcased in 30 countries around the globe.
Solutions with joist, for example, are limited to planar trusses in an array, and work in only one direction. Solutions with machined joints, such as ball-joint systems, must minimize the number of nodes, as these are expensive. Thus, some geometries become impractical even if they could result in material savings.
Geometrica's building system is versatile. It features an extruded, universal and strong joint, human-scale modules, dense packing volume, and easy installation that requires the use of minimal equipment. These virtues allow for unlimited forms. And the judicious selection of form results in beautiful and efficient long-span structures.
Time Elapsed Videography
Geometrica's structures are built with lightweight and strong galvanized steel or aluminum tubes which are prefabricated in their computer-based manufacturing system and are connected on site via patented aluminum hubs. The connection of tubes and hub is compact, simple and extremely efficient, with little (or no) welding required.

The connecting hub is an extruded aluminum cylinder with several threaded slots. Each tube is formed at the ends into a matching linear shape that slides into the hub's slot. When all the tubes in a certain hub have been assembled, the joint is completed with washers and a single bolt.
Once complete, the joint is strong, sometimes even more than the joined tubes themselves. Most importantly, the tubes resist bending moments at the joint. This allows for the deck or cladding of the structure to be affixed directly to the space frame members, without secondary structural purlins that can be as heavy as the frame itself in other construction systems. This feature also permits many variations on basic geometries that are simply not possible with conventional bolted or welded connections.
Endless Design Possibilities
Almost any structural geometry is possible with the Geometrica system, including flat and faceted space frames, singly curved arches and vaults, double curved domes and hypars and arbitrary freestyle shapes. Stay tuned to our upcoming newsletters for details about each of these geometries and their practical applications.
