Abstract:
Tensile fabric structures are efficient and cost effective structural systems for covering large areas. The performance of such structures is highly dependent on their geometry, and for this reason they must be doubly curved. However, doubly curved surfaces may not be formed from flat fabric without incurring distortions. The process of patterning is employed to determine the planar configuration of panels, such that after assembly, these distortions are minimised. However, patterning is sensitive to the numerical models and processes employed. Shear of the fabric is required for it to adopt a doubly curved shape, but this has been overlooked in the numerical models used currently for the patterning of tensile fabric structures. On this basis, a discrete element model for numerical representation of the fabric, during the patterning process, is proposed and examined in this thesis. Further to this, the computational process of patterning is examined thoroughly, and improvements to sub-processes within patterning form part of a proposed patterning method. This thesis reviews the literature relating to tensile fabric structures, patterning, and numerical modelling. The discrete model is described, along with its implementation in the proposed patterning method. Comparison with published results is included to evaluate the suitability of the proposed model and patterning method. It is shown that the proposed discrete element model offers an alternative model for architectural fabrics at the patterning stage. Conditions for successful use of the model are stated and explored. In addition to this, the proposed improvements to the patterning process are examined.
