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.

This paper is concerned with the selected aspects, which are discovered during a design stage of cable and membrane structures, known as “form-finding” process. The aim of this paper is the understanding of the basic principles of the form-finding process and their explanation of the very simple examples. The use of the finding a shape of a tension membrane that is in static equilibrium as an analogy with the search condition of minimal surfaces is explained. The basic principles are demonstrated on simple 2D example, in which the finding a stable minimal surface passes in the finding a stable minimal length.

Form-finding of tensioned fabric structure in the form of Enneper minimal surface has been investigated. Computational form-finding is frequently used to investigate the possible forms of uniformly stressed surfaces. In this study, two parameter of Enneper minimal surface was used in this study are u and v = 0.4 and 1.2. This study provides an alternative choice for engineer to consider the Enneper minimal surface, u = v = 0.4 and 1.2 to be applied in tensioned fabric structure.

The shape of membrane and cable-net structures is usually modeled by geometry of minimal surfaces. Using central finite differences method, a nonlinear iterative process for finding the minimal surface with given fixed boundary conditions is developed and implemented in Mathematica?. Having in mind form-finding of membrane structures, the results are compared with the results obtained by commercial package EASY?, made by Technet GmbH, Germany.

Form Finding Analysis

This paper presents the computational form-finding analysis of half-Costa tensioned membrane structure model in YZ-plane with different boundaries. The computational form-finding analysis is carried out based on nonlinear analysis method. The tensioned membrane structure in the form of half-Costa models in YZ-plane with different geometry have been found to converge with least square error of total warp and fill stress deviation. The outcome of this paper can serve as a reference in selecting satisfactory parameters to allow the performance increase of tensioned membrane structure in the form of half-Costa in YZ-plane respected to their boundary condition. These models will be selective forms of tensioned membrane structure for design engineers and architect to ponder on as it is a resource efficient structure hence preventing further damage to the environment.
