Experimental Verification of Fatigue Resistance of Steel Expansion Anchors to Concrete Loaded by Cyclic Tensile Force with Regard to Particular Failure Modes

Abstract

The paper deals with some questions of the actual behaviour of post-installed anchoring elements and it is oriented to the problems of the behaviour of steel expansion anchors to concrete under repeated tension loading, especially. In this connection, the paper is mainly directed towards the investigation of the strain and failure mechanism from the viewpoint of the possibilities of the resistance determination using experimental results. Specifically, this paper presents some brief information about the results of loading tests of expansion anchors loaded by the actions of cyclic tensile force, also in relation to the similar results referenced in literature.
