In architecture and structural engineering, a space frame or space structure (3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. (Wikipedia, CC BY-SA)
Space Frames are amongst the most weight efficient form of light weight steel structures. Elements and nodes are separated and bolted together to form frames. Geometrical shapes can be either curved or flat, with many variations on grid types.
structure spatiale
En architecture et en en ingénierie des structures, une armature spatiale, ou structure spatiale ou encore structure réticulaire (en anglais spaceframe) est un treillis, léger et rigide, construit à partir d'entretoises verrouillées en motif géométrique. (Wikipedia, CC BY-SA)
