Design resistance according data given in ETA-98/0001, issue Influence of concrete strength Influence of edge distance Influence of spacing / 2011 HST Stud anchor 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.
