Dynamic anchor FDA · Chemical fixings Loads Dynamic-Anchor FDA Design values for cyclic fatigue loading¹) of a single anchor normal concrete of strength class C20/25²). For the design the complete current assessment ETA-20/0206 has to be considered. Cracked and non-cracked concrete Material fixing element Type FDA 12 x 100 FDA 16 x 125 Effective anchorage depth Minimum member thickness Installation torque Design values of tension (∆NEd,max) and shear loads (∆VEd,max); minimum spacing (smin) and edge distances (cmin) with reduced loads hef hmin Tinst ∆NEd,max³) ∆VEd,max³)4) smin4) cmin4) [mm] [mm] [Nm] [kN] [kN] [mm] [mm] gvz 100 130 40 10.8 5.0 100 2005) gvz 100 200 40 10.8 5.0 100 1005) gvz 125 160 60 18.5 9.1 100 2005) gvz 125 250 60 18.5 9.1 100 100 3 ¹) The design values of the cyclic fatigue loading apply for load cycles ≥ 5 x 106 in accordance with design method I acc. to TR061 - for unknown static lower load. If the static lower load is known and / or for lower number of load cycles higher load values are possible. The partial safety factors as regulated in the design standard are considered. As a single anchor counts e.g. an anchor with a spacing s ≥ 3 x hef . The given load values apply for anchorages in dry and wet concrete and temperatures in the base material up to 50 °C (resp. short-term up to 80 °C) and drill hole cleaning acc. to assessment. ²) For higher concrete strength classes up to C50/60 higher permissible loads may be possible, see assessment. The concrete is assumed to be standard-reinforced. ³) In the case of combinations of tension loads, shear loads, bending moments with reduced or minimum spacing and edge distances (anchor groups) the design must be carried out in accordance with the provisions of the complete assessment. 4) Valid for pulsating loads. For alternating loads see assessment. 5) Without reduction of the tension and shear load. Details see assessment. 169
