Modern fastening systems are used in a wide range of construction industry. It iswell known, thatthe load bearing capacity of the various fastening systems is essentially influenced by the mechanical propertiesof the anchorage ground. Because of the increasing quantum of the application of steel fibre reinforced concrete(SFRC) for structural purposes it is urgent necessary to have safe and durable fasteners which are suitable forusage in this building material.The paper presents the investigations of the structural behaviour of various post-installed fastening systemsin steel fibre reinforced concrete (SFRC) which were performed in Leipzig/Germany. Tests of expansion andundercut anchors, as well as bonded anchors in combination with 3 different anchorage grounds have beencarried out. The used anchorage grounds were a normal concrete without fibres and two steel fibre reinforcedconcretes of similar strength in which different kinds of steel fibres were added.The results for all tested anchors show that the structural behaviour of fastenings in non of the investigatedconcretes is better. However, the scattering of the load bearing capacity of the anchors installed in SFRC is evenhigher. This fact leads to a decrease of the design values of the resistance in the ultimate limit state.
