| Summary |
Creep property is important for evaluation of durability of membrane structures. In winter, snow load is generated on membrane structures. In the case of unexpected heavy snow falling, it seems that creep property of membrane material under heavy loading is important in particular. And stresses usually are generated bi-axial direction, warp and filling direction, of membrane material. The authors made a water-pressed creep tester. The tester is considered heavy loading and tensioning to bi-axial directions. The authors carried out the test and report the results.
