Simplified design method Simplified version of the design method according ETAG 001, Annex C.
Influence of concrete strength Influence of edge distance Influence of spacing Valid for a group of two anchors. (The method may also be applied for anchor groups with more than two
anchors or more than one edge. The influencing factors must then be considered for each edge distance and spacing. The calculated design loads are then on the save side: They will be lower than the exact values according ETAG 001, Annex C. To avoid this, it is recommended to use the anchor design software PROFIS anchor)
The design method is based on the following simplification: No different loads are acting on individual anchors (no eccentricity)
The values are valid for one anchor. For more complex fastening applications please use the anchor design software PROFIS Anchor.
Tension loading
The design tensile resistance is the lower value of
a) The edge distance shall not be smaller than the minimum edge distance cmin given in the table with the setting details. These influencing factors must be considered for every edge distance.
a) The anchor spacing shall not be smaller than the minimum anchor spacing smin given in the table with the setting details. This influencing factor must be considered for every anchor spacing.

Precalculated values Design resistance calculated according ETAG 001, Annex C. All data applies to concrete C 20/25 – fck,cube =25 N/mm².Recommended loads can be calculated by dividing the
design resistance by an overall partial safety factor for action = 1,4. The partial safety factors for action depend on the type of loading and shall be taken from national regulations.
Design resistance for a single anchor, without edge effects
