ABSTRACT
The tensioned fabric structures are normally designed to be in the form of equal tensioned surface Yee (2011). Tensioned fabric structures employed membranes that have support geometry resulting in anticlastic membrane curvature, wherein outward loads are resisted by an increase in stress in the hogging warps about one axis of the membrane and inward forces are resisted by an increase in stress in the sagging warps about the other axis. Tensioned fabric structures are considered as form-resistant structures with doubly curved surfaces which must be pretension in such a way in order to resist applied environmen-
tal loading such as wind and snow. Form-finding using suitably formulated computational method has to be carried out for TFS in order to determine the initial equilibrium shape under prescribed support condition and pre-stress pattern. The principle of nonlinear analysis method is based on the large displacement finite element formulation used for analysis of structural behaviour under external loads. It can be used with suitable strategy proposed by Yee (2011) for form-finding purpose.
