The paper experimentally investigates the hysteretic behaviors of PTFE-coated glass-fiber fabrics under cyclic loading. In the experiments, two types of loading test were performed. One was a bi-axial loading test in which the tensile stress ratio of the loading was kept as constant, and another one was a shear loading test which was executed by controlling shear strain with initial introduced stresses. The specimens for both tests were cut from a same material sheet. Several different magnitudes for both stress ratio and shear strain were given to see the effects on their hysteretic loops. The results from these tests reveal the characteristics of the membrane materials. They are: (1) Bi-axial hysteresis curves are different from each other depending on the tensile stress ratio. (2) Shear hysteretic behaviors are almost independent of the magnitudes of the bi-axial pre-stress. (3) Bi-axial and shear hysteresis curves follow their same paths with cycles of loading.
