Concrete cone area of single anchor and group of anchors

The determination of the concrete cone area of a single anchor and for a group of anchors is the basic parameter to determine anchoring safety. The concrete cone area calculation is based on the ETAG 001 Annex C. The area is evaluated for each anchor in tension separately, taken into account anchoring depth and concrete block edge distance. The area of a group of anchors is then calculated as an intersection of the single areas of all
