1) This means c ≥ 1.5 x hef and s ≥ 3 x hef<br />

2) This means c ≥ 10 x hef<br />

3) The concrete is assessed as having normal reinforcement. In case of higher concrete strengths, higher resistances are possible.<br />

4) The tightening torque is not stipulated in the approval document and observance of this specification is therefore not relevant to the approval<br />

5) Failure of steel decisive<br />

The partial safety factors of the dowel resistance as well as the partial safety factors of the effect of γ G = 1.35 stipulated in the approval documents are taken into account. In case of a combined load, dowel groups as well as axle. or edge<br />
