Abstract:
Firstly, uni-tension and cycle loading tests were carried out for ETFE film. The stress and strain curve and cycling curve were analyzed thoroughly. The results indicate that ETFE is super elastic and elastic-plastic. According to form finding method formulated from force density subjected to volume constraints, design analysis procedure was developed for pneumatic structure, and specialized EasyVol was introduced for air cushion membrane analysis. Through series numerical analysis, parametric effects on equilibrium form and inter discipline were investigated for various plan form(rhombus, hexagon, rectangular, circle), such as rise, rise-to-span, differential pressure, initial prestress. Finally, structural performance analysis was performed for cushion applied wind pressure and suction, as well as parametric effects investigation. The presented works are valuable to design of ETFE air cushion membrane.
