Different fastening systems are available nowadays to transfer any given load combination into a concrete member. Bonded anchors are one of the most commonly-used systems. Their failure under tensile loading occurs in two different ways, following the formation of either a conical crack or a number of split- ting cracks. In this paper, the attention is focused on the latter failure mode, that may occur with fastenings located close to an edge or to a corner, particularly when the thickness of the member is small. The objective is to define a suitable design approach for bonded fastenings characterized by a splitting-type failure. To this end, numerical and experimental studies were carried out, the former being based on nonlinear finite-element modelling. The results are presented and discussed in this paper, together with the proposal of the afore- mentioned design approach. Finally, the analogy between the proposed approach and that adopted in the de- sign of lap splices in R/C members is discussed.
