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.

Form Finding Analysis

Nonlinear analysis method is one of the earliest methods proposed for form-finding analysis of tensioned fabric structures. However due to some inherent weaknesses, the method has not been fully developed. In this paper, computational strategies for form-finding analysis of tensioned fabric structure using the nonlinear analysis method has been proposed. For the purpose of verification, form-finding analysis on numerical examples of tensioned fabric structures in the form of minimal surfaces Catenoid, Helicoid, Scherk and Enneper have been carried out. Both the obtained shape and pre-stress pattern have been checked with classical solutions for the above minimal surfaces for verification of the effectiveness of the proposed computational strategies.

Form-finding of fabric surface bordered by Oval has been investigated. In this study, the possibility of adopting the form of Oval as surface shape for tensioned fabric structure has been studied. The combination of shape and internal forces for the purpose of stiffness and strength is an important feature of fabric surface. For this purpose, form-finding needs to be carried out. Nonlinear analysis method has been used for form-finding analysis of the fabric in the form of Oval.

This article reviews the different aspects involved in computational form finding of bending-active structures based on the dynamic relaxation technique. Dynamic relaxation has been applied to form-finding problems of bending-active structures in a number of references. Due to the complex nature of large spatial deformations of flexible beams, the implementation of suitable mechanical beam models in the dynamic relaxation algorithm is a non-trivial task. Type of discretization and underlying beam theory have been identified as key aspects for numerical implementations. References can be classified into two groups depending on the selected discretization: finite-difference-like and finite-element-like. The first group includes 3- and 4-degree-of-freedom implementations based on increasingly complex beam models. The second gathers 6-degree-of-freedom discretizations based on co-rotational three-dimensional Kirchhoff–Love beam elements and geometrically exact Reissner–Simo beam elements. After reviewing and comparing implementation details, the advantages and drawbacks of each group have been discussed, and open aspects for future work have been pointed out.

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.
