<scp>Semi?precast</scp> segmental bridges: Development of a new construction method using <scp>thin?walled</scp> prefabricated concrete elements

In order to understand the overall picture, different technologies for use of thin-walled prefabricated elements in bridge construction as well first-time application them a project Austria are described this paper. Thereafter newly developed method on-site fabrication lightweight box-shaped segments from concrete elements, strengthened with steel girders, is explained focus lying on prototype 1:1 scaling. The conceptional design, manufacturing prefabrication plant and transport site illustrated. Finally, an example new technology shown based design using incremental launching method. research confirms feasibility assembly that method, once minor constructive details will be solved ongoing project, has great potential broad construction.
