Incrementally Launched Bridges

This work provides detailed information on the basics of an important construction method for bridges: the incremental launching method. This method is characterised by the interdependence of design and construction, such as design as a result of the construction process and its specific requirements. Civil engineers should find a wealth of information on the principles and suppositions for both design and construction as well as on state-of-the-art launching equipment. Aspects of super structure and substructure are thoroughly discussed. The calculation of forces on substructure components during launching are dealt with in great detail and are illustrated by practical examples. A complete chapter analyses the requirements for precision construction. Special sections address key topics such as the coupling of tendons and the anchoring of bearings, topics that are also of interest in connection with the design of prestressed concrete bridges. Also, advantages and disadvantages of various launching techniques are critically assessed, with the durability aspect of incrementally launched bridges being considered from the perspective of design and experience.
