The members are connected with ball-and -socket joints. 6 Space Trusses Generalizing the structure of planar trusses to 3D results in space trusses. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads are transmitted as tension and compression loads along the length of each strut. Space frames can be used to span large areas with few interior supports.
