Project Details


Ultra High Performance Concrete (UHPC) has an outstanding compression strength. Thus, one of many important fields of application of UHPC is the construction of columns. However, at the present not any realisation of a classical, highly loaded column is being public. Therefore this project aims at providing the scientific basics for the practical realisation of such structures. Because UHPC allows also extra-slim designer-columns, the existing design codes have to be revised and adopted for that new application. Special focus is on the determination of the members load-carrying capacity in a way, where both is correctly considered, the physical circumstances and the aspects of the safety concept. The theoretical results are confirmed through manifold experiments known from literature. In the actually not investigated field of extra-slender columns combined with ultra high strength materials additional experiments will be performed in the scope of this project. The development of new structural details, which agree with the special demands coming from UHPC, is also part of the project work. For instance, prestressing is a very useful tool for getting improved capacity of slender high-strength columns. This bridge 1-project (FFG) is the follow up of a very close and long lasting cooperation with the Austrian construction industry, which is here presented by the SW Umelttechnik GmbH.
