Parameters affecting steel anchorages under shear

TLDR: In this article, the effect of various parameters on the load carrying capacity of steel anchors in shear was investigated, and it was found that there could be a large variation in the load capacities and the failure modes depending on embedment length and the presence of reinforcement near the anchors.

Abstract: Steel anchorages find various applications in concrete structures, including rehabilitation of deteriorated structures. Experiments were carried out to study the effect of various parameters on the load carrying capacity of steel anchors in shear, and the results compared with other published data and empirical formulae. It was found that there could be a large variation in the load capacities and the failure modes, depending on embedment length and the presence of reinforcement near the anchors. It was also found that the actual failure loads were sometimes considerably lower than the estimates given by available empirical relations.
