   [1]: 4 anchor recess A formwork blockout or recess former fitted to the edge formwork of a post-tensioned concrete member, and that creates a temporary void space external to the prestressing anchor to allow the anchor block or similar to be fitted after formwork stripping. [3]: 32 anchor set See wedge set. anchorage assembly

3. Anchorage in reinforced concrete - Wikipedia

   en.wikipedia.org/wiki/Anchorage_in_Reinforced...

   Because the actual bond stress varies along the length of a bar anchored in a zone of tension, most international codes of specifications [2] [3] [4] use the concept of development length rather than bond stress. The same concept applies to lap splice length mentioned in the codes where splices (overlapping) provided between two adjacent bars ...

   They can be further divided into two categories: [3] torque controlled: the anchor is inserted into the hole and secured by applying a specified torque to the bolt head or nut with a torque wrench. A particular sub-category of this anchor is called wedge type. As shown in the figure, tightening the bolt results in a wedge being driven up ...

   For example, a footed pin head style anchor maybe more susceptible to edge distance than a hairpin style anchor. Or a splayed anchor does not have the same tensile/axial capacity with the equivalent anchor length (effective embedment is greater on a footed anchor than a splayed anchor of equivalent overall length, see figure 4).

6. Offshore embedded anchors - Wikipedia

   en.wikipedia.org/wiki/Offshore_embedded_anchors

   A deep-penetrating anchor (DPA) is conceptually similar to a torpedo anchor: it features a dart-shaped, thick-walled, steel cylinder with flukes attached to the upper section of the anchor. A full-scale DPA is approximately 15 metres (49 ft) in length, 1.2 metres (4 ft) in diameter, and weighs on the order of 50–100 tonnes (49–98 long tons ...

7. Concrete cone failure - Wikipedia

   en.wikipedia.org/wiki/Concrete_cone_failure

   The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
