Form-Finding with and without Cable Reinforced Thomsen Surface in Tensioned Fabric Structure

Abstract

Abstract Tensioned Fabric Structure (TFS) is structure that is composed of tensioned fabric as structural members. The form of Thomsen surface applied in TFS has been developed in this study because the form of Thomsen surface has not been studied by others researcher. The objective of this study is to determine initial equilibrium shape in Thomsen form and cable reinforced of Thomsen surface in TFS with variable u=v=0.8 using nonlinear analysis method. The surface of Thomsen surface, u=v=0.8 shows the least square error of total warp and fill stress deviation is less than 0.01. From the result, initial equilibrium shape in Thomsen form and cable reinforced of Thomsen surface, u=v=0.8 is corresponding to equal tension surface. In conclusion, Thomsen form and cable reinforced of Thomsen surface with variable u=v=0.8 will provide an alternative shape for designer to be considered for adopted in tensioned fabric structure.
