Large Span China Design Steel Space Frame Aircraft Hangar These represent one of the more efficient uses of structural materials. Space frames are three dimensional lattice-type structures that span in more than one direction. It is common practice to apply the "space frame" designation to structures that would more accurately be categorized as "space trusses", that is, assemblies of members pin-connected at the joints, or nodes. In addition to providing great rigidity and inherent redundancy, space frames can span large areas economically, providing exceptional flexibility of usage within the structure by eliminating interior columns. Space frames possess a versatility of shape and form. They can utilize a standard module to generate flat grids, barrel vaults, domes, and free-form shapes. ...
