    Behaviour of fasteners under monotonic or cyclic shear displacements
    (1991) Vintzéleou, Elizabeth; Eligehausen, Rolf
    An experimental program was carried out to investigate the behaviour of metallic fasteners (undercut, torque controlled expansion and chemical anchors) embedded in cracked concrete and subjected to shear displacements, under shear displacements is similar. Fasteners situated close to an edge and loaded towards the edge exhibit brittle concrete failure. Cyclic loadings are possible only for displacements which are much lower than the values corresponding to the monotonic peak load. Fastenings away from an edge will cause steel failure with large displacements. During cyclic loading, a severe force-response degradation was observed. Empirical formulae are proposed to predict the strength of anchors, as well as strength degradation during cyclic loading.

    Behaviour of metallic anchors under generalized excitations
    (1989) Eligehausen, Rolf; Vintzéleou, Elizabeth
    In this paper are briefly presented the results of an experimental program which was carried out with the aim to investigate the behaviour of several types of metallic anchors (undercut, expansion and chemical anchors) under both monotonic and cyclic shear actions. Several parameters were investigated within the program, namely: the presence of cracks crossing the anchor, the distance of the anchor from the free edges of the concrete section, the presence of transverse reinforcement, the loading history, etc. The influence of these parameters on the mechanical characteristics of anchors is illustrated in this paper, while empirical formulae for the calculation of the maximum shear force vhich may be transferred by metallic anchors are given.
