| Summary |
Structural stability of membrane structures are retained by geometrical stiffness due to pretension on membrane material. Therefore introduction of prestress during construction and maintenance after completion are important. Though membrane materials consist of woven fabric and plastic coating tend to occur creep and stress relaxation. Clarifying mechanical characteristic and state of stress transfer of welded part and crumping part as well as membrane materials is necessary to accomplish balanced design and maintenance of membrane structures. Uniaxial tensile experiment and analysis considering material nonlinearity of membrane materialEwelded part and crumping part are executed on this paper.
