Abstract

The prefabricated deployable space frames investigated in this work are "smart" structures in the sense that they have the ability to adapt to changing needs by using the, usually destructive, snap-through phenomenon as a form of prestressing. Their design is very challenging due to the need to balance the conflicting requirements of desired flexibility during deployment and desired stiffness under service loads. This paper describes a first effort to escape from a heuristically driven, manual design by employing optimization via a genetic algorithm. 1 Introduction Deployable structures are prefabricated space frames consisting of straight bars linked together in the factory as a compact bundle, which can then be unfolded into large-span, load bearing struct
