Abstract: The failure of a fastening is often caused by a rupture of steel, anchor pullout or by a concrete-cone failure. In the past these failure modes have been intensively investigated and the associated failure loads can be calculated with sufficient accuracy [1]. For the failure mode splitting there exists no general equation to calculate the failure load.
Therefore, theoretical and experimental investigations have been performed [2]. Splitting of a concrete member can be expected if the member dimensions are relatively small or in large concrete specimens if the fasteners are installed near to an edge or corner. The splitting failure load depends on dimensions and on material properties of the concrete member. Moreover, the design and load-bearing area of the fastener influence the failure load as well.

In the present paper the results of experimental and numerical investigations in case of splitting are discussed and a design method to calculate the splitting failure load is proposed. Details of the design method are given to illustrate how installation parameters (dimension of concrete member and material properties) and the type of the fastener (headed anchor and undercut anchor) influence the splitting resistance.
