A computationally efficient method is presented for approximate optimization of cutting pattern of frame-supported and pneumatic membrane structures. The plane cutting sheet is generated by minimizing the error from the shape obtained by reducing the stress from the desired curved shape.The equilibrium shape is obtained solving a minimization problem of total strain energy. The external work done by the pressure is also incorporated for analysis of pneumatic membrane. An approximate method is also proposed for analysis of an Ethylene TetraFluoroEthylene (ETFE) film, where elasto-plastic behavior is modeled as a nonlinear elastic material under monotonic loading condition. Efficiency of the proposed method is demonstrated through examples of a frame-supported PolyVinyl Chloride (PVC) membrane structure and an air pressured square ETFE film.

Current research regarding fabric structures focuses largely on characterising the complex nonlinear material behaviour [1][2][3] and the testing methodologies used to determine the material properties [4][5][6][7]. Due to the material complexity and wide variety in computational modelling methodologies and results [8], as well as practical limitations, only few sources have compared computational results to full scale experimental verifications.…”

a b s t r a c tTechnical textiles used in lightweight tensile fabric structures are inherently highly flexible, which makes these materials very suited to, for instance, make lightweight adaptable façade or roof systems.Until now, however, kinematic fabric structures are mostly designed to transform between a prestressed, structural state and a compact state where the fabric becomes untensioned using fixed geometrically determined paths. The goal of this research is to design and validate the structural behaviour of a kinematic fabric structure which remains prestressed in all its possible geometric states by taking advantage of the out-of-plane flexibility of the material rather than the high stretchability.To make the design and the use of such a kinematic fabric structures possible, we investigated the material properties of a standard polyester-PVC fabric. Afterwards, we implemented these properties in a computational model and performed a parameter study to come to a conceptual design of a kinematic prestressed fabric structure where its geometry follows the reorientation of forces rather than restricting its movement to a geometrically determined path. Finally, the designed kinematic structure was built and tested as a prototype, comparing reaction forces and strains to the ones predicted in the computational model. This paper describes this experimental validation by comparing the experimentally obtained results to the values predicted in the computational simulations using a cable-net approximation and a linear elastic orthotropic material model.Although this comparison showed some deviations in the absolute values of the forces and strains, the general behaviour of the prototype was correctly predicted using a standard analysis method. The majority of the deviations could be contributed to the fact that the strains in the computational model do not take into account the compensation applied to the prototype and the high permanent straining of the boundary belts.The investigated prototype thus showed both the potential and the difficulties of using lightweight, highly flexible fabrics as structurally stable, kinematic elements.
