Actual Behaviour and Objective Load-Carrying Capacity of Tension Steel Expansion Anchors to Concrete

This paper deals with some selected problems of anchoring systems with the steel mechanical expansion anchors to concrete and it is based on experimental research oriented to these elements under repeated tensile loading in particular. For this non-monotonic kind of loading there are no values of carrying-capacities determined yet. But, there is a possibility to use the cyclic loading force during the tests and after that to compare the values of resistances to theoretical values for static loading. Thus, here are presented some results of this research, which was especially focused on actual behavior and load-carrying capacity determination of these members.
