Notes:
The aim of this research is to find a feasible method for the estimation of the tensilebehaviour of woven membrane construction materials under bi-axial loading. During the modeldevelopment, the woven membrane materials are treated as orthotropic, elastic and linear. Based onthe constitutive relationships for orthotropic and elastic materials, two equations sets are deducedfor the estimation of modulus in the warp and the fill direction respectively when suffering from thebi-axial loading. To checkout the validity of the estimation, seven groups of biaxial tensile testswith stress ratios of 1:0, 1:1, 2:1, 5:1, 1:2, 1:5 and 0:1 have been carried out on two kinds of PVCcoatedwoven membrane materials. From the comparison of the experiments and the prediction, itcan be noticed that the model can achieve ideal results when it comes to the estimation of modulusin the leading direction, which is the direction with a higher stress than the other one. Therefore,based on the hypothesis of orthotropic, elastic and linear materials, there is an easy way to estimatethe bi-axial tensile properties of woven membrane materials in the leading direction only throughthe uni-axial tensile tests
