groups in the last decade allowed the validation of the effectiveness of the plane
biaxial test based on cruciform samples (Reichard et al.

), the analysis of the prin-
cipal parameters involved in a testing procedure (Bridgens

of innovative models of calculus and representation (Bridgens and Gosling

) and the reliability of the current procedures and equipment
(Uhlemann et al.
2011
; Beccarelli et al.
2011
; Bridgens et al.

).
At present, the main research area concerns the development of an international
testing standard able to integrate the testing procedure developed by the Membrane
Structures Association of Japan (MSAJ/M-02:
1995
; Bridgens and Gosling
2010
).
The European Committee for Standardization (CEN TC248 WG4) is evaluating the
draft for a standard on the mechanical biaxial stiffness and strength properties, and
the shear and the tear strength of coated fabrics for architectural tensioned covers.
Other test campaigns will be presumably required by the development of parts for
the future Eurocode 10 concerning material properties and their modelisation (CEN
TC250 WG5). The main open issues are the biaxial and shear behaviour of the
fabric in correspondence with the initial conditions, under service conditions and at
breaking point, the ef
ö
cacious and exhaustive representation of the results and,
finally, the validation of the mathematical models at different levels of accuracy and
computational speed.
