Abstract

Form-finding of fabric surface bordered by Richmond’s has been investigated. In this study, the possibility of adopting the form of Richmond’s as surface shape in tensioned fabric structure under different prestress values 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 Richmond’s minimal surface. Richmond’s minimal surface models are analyzed with two different values of prestress which are 3000N/m and 5000N/m. The average warp and fill stresses deviation for all models presented are less than 0.01 which indicates the model can serve as reference to the engineers or architects in the selection of proper surface parameter to achieve a structurally viable surface. As a result, this study is expected to lead the improvement of rural basic infrastructure, economic gains, sustainability of built environment and green technology initiative.
