Smart bridge design concept to rebuild up deployable bridge based on post-buckling theory

In this paper the micro truss technique that relates to this topological optimization is used as a way to decide on the form of a bridge. The design and production of and experimentation on a prototype of the Mobilebridge, whose structure was determined by looking at the digital optimum structure in the figure, were executed. And the potential application of this bridge was estimated. It seems that a design with a high degree of freedom becomes possible and is useful in terms of structural engineering when using the present analytical method to determine the design and material to use for the structure. This paper describes a bridge design that was determined using a folding technology according to an original grand-structure method. This bridge considered compression buckling that occurs when a micro-truss is used on a large scale. In this way, the optimum folding structural form for an emergency bridge was created by using this computing method. A prototype bridge that had this structural form was actually produced. It was experimented on to examine its mechanical behaviour by subjecting it to a nondestructive load (coming from the weight of people). We have carried out a comparative investigation by conducting a basic experiment on this folding structure to examine the design and production of this new bridge.
