In view of the trend of constructing buildings increasingly bigger, wider, and taller, the limits of conventional reinforced concrete columns are already being reached. Therefore, in high-rise construction, intriguing areas of application come up for high-performance materials currently used primarily in the field of research. One of these areas of application involves high loaded reinforced concrete columns, where such components can be realised by substituting conventional materials with the mentioned high-performance building materials. The development of high-performance materials enables the construction of slim columns, which in turn leads to material-, spaceand resource savings. Thus, under the right conditions, high-performance columns can be used more cost-efficiently than conventional reinforced concrete columns. In the course of this diploma thesis the use of high strength steel SAS 670/800 and ultra high performance concrete (UHPC) is investigated. The current normative regulation for reinforced concrete columns in the EN 1992-1-1 allows a maximum compression of 2.00h. Therefore, the high-strength steel SAS 670/800 cannot be strained up to its yield point and would hence be uneconomical as pressure reinforcement. Due to creep in the concrete, there is a load redistribution from concrete to steel. By taking advantage of this phenomenon, a higher degree of utilisation of high-strength steel can be achieved. Another problem arises in the column-slab joint when transmitting high loads through the slab. Because of the different concrete strengths, stress concentrations occur in the slab joint. Building on this issue, the Vienna University of Technology has developed a patent for a column-slab joint, which enables a better transmission of loads. Finally, different column slab joints are calculated through an FE analysis. The obtained findings provide respectable values for further investigations.
