Abstract: In the present paper the numerical results for the splitting failure mode which is typical for fastening elements that are used too close to the member edges or in a narrow concrete members are presented and discussed. To investigate the influence of the size and geometry on the splitting failure, three-dimensional FE analysis was carried out. In the analysis the nonlocal mixed formulation of the microplane model for concrete was used. The splitting fracture is generated by imposing controlled concentrated radial displacement in the hole of the anchorage element. Geometrical parameters of a concrete specimen (width and thickness), the size of the relatively small loading area (diameter and height) as well as the embedment depth of the fastening element are varied. The analysis shows a strong size effect on the ultimate pressure at splitting failure and good agreement with experimental observations.
