Abstract: The so-called ortho-composite-slab combines the orthotropic stiffened steel deck as a lightweight construction for medium and long span bridges with the robustness of composite slabs to handle increasing traffic loads. The structure consists of an orthotropic stiffened steel deck, a relatively thin layer of reinforced concrete and dowel strips with teeth in the form of clothoids as shear connectors . In addition to the significant advantages of low deadweight and long service life, the ortho-composite-slab is characterized by fast and economical production. The construction was investigated by a comprehensive experimental test program in combination with structural-mechanical calculations as part of the AiF-FOSTA research project P 1265 at the TUD Dresden University of Technology. Within the scope of the project, basic principles for the design of ortho-composite-slabs with dowel strips were developed. This paper first gives an overview of the experimental test program. This is followed by a detailed discussion of the static and cyclic tests on sections of the ortho-composite-slab (so-called beam tests). The statistical evaluation of the tests and the assignment to a fatigue resistance curve are presented.
