This paper discusses a novel typology for medium span mobile bridges: the piston stayed bascule bridge. The Temse bridge over the river Scheldt (Belgium) illustrates this system. This competition winning project runs 374m over seven fixed parts with spans varying between 18 and 74 m and two mobile spans of 28m. The design considerations and the structural static and kinematic system for this project are discussed. The main design idea is “structural integration” namely that one element fulfils more than one function. The structural innovation lies in the use of the piston stay that doubles up as static structural element and as a kinematic actuator. Combined with counterweights, this structural system presents a new and elegant solution for mobile bridges. |
