Abstract
The design of anchor fastenings in concrete is dealt with in EN 1992-4 [1] only for simple anchor layouts (Figure 1). For fastenings with gap in the fixture near the edge under shear load towards to the edge, maximum of two anchors in a row parallel to the edge can be designed. In the case of fastenings under torsional moment, the resistance of the anchor group for the concrete edge failure mode cannot be calculated according to the current regulations [1-5] because the resulting anchor shear force in the group is equal to zero.
In order to extend the application range of fastenings beyond regulated simple anchor layouts, a design model for the failure mode of concrete edge failure for arbitrary anchor groups under arbitrary shear load and torsional moment is developed. The design model is verified by 30 test results.
In this paper, the design model is presented and explained with design examples.
