Abstract

The tensile performance of construction membrane materials under multi-axial loads is focused on the present study. Two groups of experiments are carried out to investigate the influences of the configuration of the specimen and the displacement speed on the multi-axial tensile properties of the materials. The configuration of the specimen for the multiaxial tensile tests is identified as gear-shape with large arm widths. It is validated that a displacement speed of lower than 20mm/min is preferable to obtain the tensile properties of the construction membrane materials under multi-axial loads. The tensile performances of construction membrane materials under uni-, bi- and multi-axial loads are compared. It shows that the tensile performances under bi- and multi-axial loads are much better than those under uni-axial loads. Therefore, for the application of construction membrane materials in lightweight structures, bi-axial or multi-axial loading conditions will be necessary.
