Influence of textile membrane on stability of supporting steel arch
Result description
In the last few decades, the membrane textile surface structures became popular not only because of their visual attractiveness, but also as a light fully-load carrying systems. In comparison with use of a traditional roof decking these structures are much more economical and attractive. However, the complex analysis and computational design methods are difficult and still not codified. The real physical model of a membrane structure supported by two inner steel arches and covering a concert stage was constructed and tested in the laboratory of CTU in Prague. The membrane used was the common Précontraint 702S Ferrari prestressed textile membrane with PVC coating. The arches were hot-formed in a workshop from Grade S355J0 steel. The paper presents experimental results of behaviour: i) isolated inner arch, ii) complex structure of the membrane with supporting arches, both under symmetrical and asymmetrical loading. In the following is presented numerical nonlinear FEM model created in SO
