1) For edge distances cmin < c ≤ ccr ccr, the recommended loads can be determined by linear interpolation.
2) The permissible loads apply to the anchor pair. The permissible load for the most highly loaded anchor must not exceed the values specified for single anchors. For anchor pairs
with axial spacings smin < s < scr the permissible load may be determined by linear interpolation, whereby for the limit s = scr, twice the permissible load for single anchors may be
applied for the anchor pair with central load distribution.
