Abstract

Most bridges are fixed structures designed to provide continuity in roads, railways or any other kind of network systems. Nevertheless in some cases the design of the bridge or traffic requirements at the bridge’s location involves some level of mobility to the structure. In this paper, two examples of non fixed structures, namely movable bridges and launched bridges, are described. In both cases several examples are posed and the circumstances related to the conception and the design of these constructions are described. Keywords: movable structures, launched bridges, innovative bridge design, design optimization.
