A Computational Study on Tensioned Fabric Structure in the Form of Richmond’s

Abstract

Computational form-finding analysis need to be carried out for tensioned fabric structure in order to determine the initial equilibrium shape under prescribed pre-stress and boundary condition. Tensioned fabric structure is highly suited to be used for realizing surfaces of complex or new forms. However, research study on a new form as a tensioned fabric structure has not attracted much attention. Alternative source of inspiration of minimal surface which could be adopted as form for tensioned fabric structure is very crucial. The aim of this study is to investigate initial equilibrium shape of tensioned fabric structures in the form of Richmond’s minimal surfaces using nonlinear analysis method. The study proposes an alternative choice for engineer to consider the Richmond’s minimal surface withr=0.24,t=1.31;r=0.34,t=1.21andr=0.44,t=1.11 applied in tensioned fabric structure. The results on parameter range in Richmond’s minimal surface can serve as a reference for proper selection of surface parameter for achieving a structurally viable surface.
