24/7/2008 · I just finished designing a tiedown anchor job where I needed 13' of rock bond. The plans called for 20' minimum. My mass stability analysis said I needed 27' of rock bond to provide a SF of 2. If I did not provide the unbonded length, then the tendon would have to elongate to resist the design load when needed.

Determining Anchor Length – Williams Form Engineering Corp.

Determining Anchor Length – Williams Form Engineering Corp.

This will typically provide a conservative anchor design. The length of a mechanical rock anchor can be shorter than a cement grout or resin bond system since the load is being transferred by a mechanical head assembly rather than a grout or resin bond length. Therefore, the free-stress length plus the length of the mechanical head assembly makes up the embedment depth of …

Tiebacks/Anchors & Soil Nails

Anchor Basics • Tieback = Anchor • An anchor is a tension support, which limits movement from subsequent excavation by providing a pre-loaded condition to the supported ground. • Tensile load is transmitted by a steel tendon made of individual strands or bars. The tendon is bonded to competent rock or soil by cement grout.
