Abstract
A novel tensioned membrane structure of striking form named as the butterfly-shape structural system has been proposed. Basic design concept and versatility of the system to create various structural forms are explained. Erection procedure of the structure for fast-track construction is presented. An innovative deployable cable-strut structure is proposed for rapid construction of large span arches. Parametric studies are carried out to investigate the structural efficiency of two-wing buttefly structure to obtain the optimum span-depth ratio, number of module, and inclination angle of the arch. Finally, assembly process and cost implication of the butterfly structure are discussed. Advantages of such structures are explored and their potential uses for space enclosure are identified.
