Abstract
The mechanical behaviour of ETFE foils used in civil engineering for tensile structures such as roofs and claddings is investigated under uniaxial and biaxial loading. Three commonly used test methods are compared: uniaxial tension, biaxial extension of cruciform samples and bubble inflation (bursting test). The study is focused, in particular, on the determination of the mechanical properties from the experimental data. After adequate data processing, all methods are found to produce very similar results. The choice of a test procedure depends, therefore, on its advantages and limitations, which are discussed. The opportunity of using finite element calculations to predict the material behaviour is also discussed and some indications are given concerning the material models that will be suitable for design analysis of ETFE foils.
