Space frames

Space structures are efficient three-dimensional structural assemblies which can take a variety of forms.

Space structures are three-dimensional assemblies of linear members in which the interconnections are such that a load at any point is distributed in all directions throughout the assembly. With the loads spread, member sizes can be decreased which makes them an efficient and economic solution to long spans. They can take the form of flat double-layer grid structures or braced domes and vaults.

An example of the former is the McCormick Place Convention Centre in Chicago by C.F. Murphy Associates which has a 2-way lattice grid roof covering 410 x 180m whilst the Louisiana Superdome in New Orleans by Sverdrup and Parcel Associates with its 206m clear span demonstrates the potential for the curved forms.
