GENERAL PRINCIPLES:

- Characteristic values according to ETA-16/0600. - Design values can be obtained from characteristic values as follows: R d = R k / γ m . Coefficients γ m are listed in the table in accordance with the failure characteristics and product certificates. - Admissible values (recommended) are evaluated based on the characteristic values by applying the material safety factors γ m according to ETA and a further partial factor for external actions γ f = 1,4. - For the calculation of anchors with reduced spacing, or too close to the edge, please refer to ETA. Similarly, in case of fastening on concrete-supports with a better-grade, limited thickness or a thick reinforcing layer please see ETA. - For the design of anchors subjected to seismic loading refer to ETA and to ETAG 001 (Annex E and TR045). - For specifications of the diameters covered by the various certifications (cracked concrete, uncracked concrete, seismic applications, masonry), please refer to ETA.

NOTES:

(1) For the calculation of anchors in masonry or in case of high bond rods, please see ETA document. (2) Pull-out and concrete cone failure. (3) Steel failure for 5.8 grade rods and variable failure mode (steel failure / pull-out) for 8.8 grade rods. (4) Steel failure mode. (5) Tensile-strength increment factor (excluding steel failure) for both cracked and uncracked concrete. (6) Pry-out failure mode.
