		¹⁾ The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of γF = 1.4 have been taken into account. For information on combining tensile and shear loads, on the influence of the edge distance, and on anchor groups, please refer to the European Technical Approval Guidelines (ETAG), Annex C. ²⁾ The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. ³⁾ For Würth W-HAZ-SK/S
