Permissible loads in concrete

1.1 Permissible maximum loads for a single anchor for fastening in cracked and non-cracked concrete
according to ETA 05/0010 and ETA 05/0011.
(The whole approval document must be observed for the design.)

1) This means c ≥ 1.5 * hef and s ≥ 3 * hef
2) This means c ≥ 10 * hef
3) The concrete is prepared as normally reinforced. Correspondingly higher resistances are possible with higher concrete strengths
4) The tightening torque is not defined in the approval document; the observance of this specification is therefore not relevant for the approval
5) Steel failure is decisive factor *) The partial safety factors for the anchor resistances defined in the approval documents as well as a partial safety
factor for the influence of γG = 1.35 have been taken into account. In the case of coups andombined loads, anchor gr also axial or edge effects,
please note the requirements for the design procedure A in Appendix C of the ETAG or our design aid
