Membrane materials have properties of material nonlinearity and stress relaxation, due to slackness and crimp interchange of yarns and viscoelastic characteristic of coating material. The stability of Tension Membrane Structures (hereafter TMS) depends on existing prestress in the membrane. The purpose of this paper is to establish the structural analysis method applied a model of stress-strain curves considering stress relaxation of membrane materials. The full-scale experiment of the TMS with spring-strut system is compared with the present analytical results. The agreement between the analytical results and the experimental results are obtained in the structural behavior under loading and unloading.
