A space frame is a lightweight and highly efficient structural system made of interconnected beams or struts forming a three-dimensional network of triangles or geometric shapes. It can span large distances without the need for internal supports, and is used in applications such as large building roofs, bridges, and towers. It requires careful planning and engineering for stability and safety. Space frames are a common feature in modern building construction; they are often found in large roof spans in modernist commercial and industrial buildings. A space frame or space structure is a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports.
