Anchors in a non-structural system based on a redundant design in concrete: European Technical Approval ETA-12/0029
- Dimensioned in accordance with the European Technical Approval Guidelines (ETAG) for "Metal Anchors for Use in Concrete", Appendix C, design method C
- Anchorage with European Technical Approval in cracked concrete (concrete tensile zone) and non-cracked concrete (concrete compression zone)
- The anchor has European Technical Approval for use in reinforced or unreinforced normal weight concrete with a strength class of min. C20/25 and max. C50/60 in accordance with EN 206-1:2000-12
Fire resistance: R30, R60, R90, R120 (base material: concrete C20/25 to C50/60): Technical Report TR 020 "Evaluation of anchorages in concrete concerning resistance to fire" (included in ETA-12/0029)
Anchors in a non-structural system based on a redundant design in concrete (for all load directions)
The partial safety factors of the resistances regulated in the approval and a partial safety factor of the effects of YF = 1.4 have been taken into account. Please refer to the European Technical Approval Guidelines (ETAG), Appendix C, for information on combining tensile and transverse loads, influence of the edge distance and groups of anchors.
Permissible load when exposed to fire
The partial safety factors for load-bearing capacity on exposure to fire of YM,fi = 1.0 as recommended in the approval and the partial safety factor of the effects of YF = 1.0 have been taken into account.
Nominal drill diameter and diameter of cutting edges of the drill
Tungsten carbide hammer drill bits must comply with the specifications set out in the information leaflet of the Deutsches Institut für Bautechnik (German Institute of Civil Engineering - DIBt) and the Association of German Tool Manufacturers (FWI) on the "characteristic values, requirements and tests for masonry drill bits with tungsten carbide cutting body which are used for the manufacture of drilled holes for anchoring". Würth hammer drill bits meet the specifications set out in the information leaflet.

Please refer to the European Technical Approval Guidelines (ETAG), Annex C, for information on combining tensile and shear loads, influence of the edge distance and groups of anchors. 2) The partial safety factors for load capacity under exposure to fire of γM,fi = 1.0 and the partial safety factor of the actions of γF = 1.0 have been taken into account. 3) Tungsten carbide hammer drill bits must comply with the specifications set out in the information leaflet of the Deutsches Institut für Bautechnik (German Institute of Civil Engineering - DIBt) and the Fachverband Werkzeugindustrie e.V. (Association of German Tool Manufacturers - FWI) on the characteristic values, requirements and tests for masonry drill bits with tungsten carbide cutting body which are used for the manufacture of drilled holes for anchoring. Würth hammer drill bits meet the specifications set out in the information leaflet. 4) Number of attachment points ≥ 3 and at least one anchor per attachment point produces a load per attachment point of Fzul ≤ 1.4 kN or number of attachment points ≥ 4 and at least one anchor per attachment point produces a load per attachment point of Fzul ≤ 2.1 kN. The admissible loads can be increased if the design shows that the requirements governing the strength and rigidity of the component to be attached remain satisfied even after the failure of an anchor in terms of the limit state of serviceability and load-bearing capacity. | ||
