Application

Application area

Individual fixing point with approval

Normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete, seismic performance category C1 and C2)

¹⁾ The partial safety factors of the resistances regulated in the approval and a partial safety factor of the effects of γ_F = 1.4 have been taken into account. Please refer to the European Technical Approval Guidelines (ETAG), Appendix C, for information on combining tensile and shear loads, the influence of the edge distance and groups of anchors. ²⁾ The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. ³⁾ The use is limited to the anchorage of statically indeterminate systems.
