Tieback anchor capacity

Tieback anchor capacity

Tieback anchor capacity

(OP)
How you determine the tieback ground anchor capacity or skin friction for single or multiple level anchors? I am consultant submit equation but no reference was provided and FHWA does not provide equation to determine the pull out capacity of anchor.

RE: Tieback anchor capacity

Pretty sure FHWA does provide this equation some where.

Its also very easy to find via google may papers, even example calc include a method to calc it.

Its a skin friction calculation, similar to a pile with some additional factors.

RE: Tieback anchor capacity

If you are designing ground anchors and anchored walls, get a copy of PTI's Recommendations for Prestressed Rock and Soil Anchors.
