Abstract

This thesis is primarily concerned with the formation of curved space trusses of various forms derived from a flat configuration by means of post-tensioning. In order to obtain a fairly general picture of the shape-formation process by means of post-tensioning, the geometrical forms investigated cover a wide scope, rather than one type in detail. Three types of curved space trusses are considered: barrel vaults, domes, and hypars. The structural performance and ultimate load behaviour of the models are also investigated as a secondary objective. The results of experimental and theoretical work on the shape formation of curved space trusses by means of post-tensioning will be presented herein.
