=== Braced dome ===
A single or double layer [[space frame]] in the form of a dome,{{sfn|Makowski|1962|p=62}} a ''braced dome'' is a generic term that includes ''ribbed'',{{sfn|Chen|Lui|2005|pp=24–18}} ''[[Johann Wilhelm Schwedler#Schwedler cupola|Schwedler]]'',{{sfn|Chen|Lui|2005|pp=24–18}} ''three-way grid'',{{sfn|Chen|Lui|2005|pp=24–18}} ''lamella'' or ''Kiewitt'',{{sfn|Chen|Lui|2005|pp=24–18, 24–19}} ''lattice'',{{sfn|Ramaswamy|Eekhout|2002|p=141}} and ''[[Geodesic dome|geodesic]] domes''.{{sfn|Chen|Lui|2005|pp=24–2, 24–18}} The different terms reflect different arrangements in the surface members. Braced domes often have a very low weight and are usually used to cover spans of up to 150 meters.{{sfn|Saka|2007|p=595}} Often prefabricated, their component members can either lie on the dome's surface of revolution, or be straight lengths with the connecting points or nodes lying upon the surface of revolution. Single-layer structures are called ''frame'' or ''skeleton'' types and double-layer structures are ''truss'' types, which are used for large spans. When the covering also forms part of the structural system, it is called a ''stressed skin'' type. The ''formed surface'' type consists of sheets joined at bent edges to form the structure.{{sfn|Makowski|1962|p=62}}
