Mechanized and automated production methods are becoming increasingly important for bridge construction and civil engineering. Composite steel-concrete construction is highly attractive because of the optimal uses to which both materials can be put and the possibility of prefabricating large parts of the load bearing structure.
In building and industrial construction, lattice-girder floor slabs and double-wall elements have been successfully used for years. These semi-precast elements of 5-7cm thickness serve as permanent formwork for the subsequently added in-situ concrete. The advantages of this construction method are planned to be applied in bridge construction and civil engineering as well. Toward that end, a research project was implemented at the Institute of Structural Engineering-Concrete Construction at Vienna’s University of Technology in collaboration with the Association of Austrian Concrete and Precast...
