Anchor channels typically consist of a steel channel section cast into a concrete member at the location where a fixing or a number of fixings in a line are required. Anchor channels are designed according to BS EN 1992-4. The CivilWeb Concrete Anchorage Design Spreadsheet does not include the design of anchor channels.
Anchor channels are also installed before or during the casting of the concrete. They typically consist of a row of bolts anchoring a channel on the surface of the concrete which is then used to connect the external fastenings.
Anchor Channel Design Verifications Required
The following design checks are required for anchor channels under tension. Follow the links for detailed explanations of each design check.
- Anchor Failure
- Failure of the connection between the anchor and the channel
- Local flexure of the channel lip
- Special screw
- Flexure of the channel
- Anchor Bolt Pullout Failure
- Concrete Cone Failure
- Concrete Splitting Failure
- Concrete Blowout Failure
- Supplementary Steel Failure
These verifications are also shown in the below table.
The following design checks are required for anchor channels under shear loading. Follow the links for detailed explanations of each design check.
- Steel Bolt Failure in Shear
- Concrete Pryout Failure
- Concrete Edge Failure
- Supplementary Steel Failure
These verifications are also shown in the below table.
