“…Extended reviews of inflated membrane applications were made by Bulson (1973), Herzog (1976) and Bernasconi and Reibaldi (1986), whereas fabrication and construction details were described by Sobek and Speth (1995). In the area of membrane fabric material, Karwath et al (2007) applied orthotropic material constitutive equations and conducted tension experiments in order to extract in-plane stiffness parameters of woven membrane materials under variable ratios of in-plane loading, whereas Bridgens and Gosling (2004) presented two methods for fitting the direct stress-strain representation of coated woven fabrics under biaxial tension. In the area of airbeams, Topping (1963) and Douglas (1969) studied the static response under bending loads, whereas the problem of wrinkling was initially studied by Comer and Levy (1962), Webber (1982) and Main et al (1994).…”

Effect of Fabric Webs on the Static Response of Spindle-Shaped Tensairity Columns

et al. 2010

Tensairity is a lightweight structural concept comprising struts and cables stabilized by a textile membrane, which is inflated by low pressurized air. This paper addresses the effect of fabric webs inside the membrane hull on the static response of spindle-shaped Tensairity columns to axial compression. Two full-scale spindle-shaped columns, one without and one with webs, were fabricated and tested. The columns were subjected to axial compressive loading for various levels of internal air pressure in order to quantify its effect on the global structural response. It was found that the stiffness and the load bearing capacity for both columns increased with increasing air pressure. The experimental results also revealed the benefits of including fabric webs in the spindle configuration in terms of axial stiffness and buckling load. Comparisons with an analytical solution and finite element predictions showed good correlation for the axial stiffness in the case without webs. For the case with webs deviations between predicted and experimental results indicated that structural detailing and imperfections in the manufacturing process strongly influence the performance of Tensairity columns with internal webs.

Mobile flood protection by use of technical textilesThe use of technical textiles for mobile flood protection is excel, especially if there is a short warning time in case of emergency flood events. This paper describes the transmission of textile building construction basics (textile roofs of stadiums and swimming pools) to the development of water-filled protection systems as an alternative to sand bag systems. It is shown that the investigations of material behavior of coated fabrics and the typical approach of membrane structures in architecture, such as form-finding, structural analysis and cutting pattern can be used to develop mobile flood protection systems. The following article manifests how this methodological approach is a suitable tool for the design of two selected flood control systems and is adapted to the specific requirements. The requirements and the selection of applicable materi als, technical textiles in particular, are discussed. It describes the form finding of membrane shells under hydrostatic stress and illustrates in detail a static analysis of such a system. The procedure of the simulation of such problems by means of a supporting structure planning computer program will be presented by expanding the bound ary conditions with the use of additional tools. The correctness of the procedure is ensured by experimental verification of the simulation results.
