RES2020-14: Design Considerations and Limitations of Rock Dowels/Anchors Loaded in Shear

The purpose of the project is to investigate the relationship between rock joint thickness and reduced dowel shear capacity due to bending in untensioned dowels used to prevent rock slides. Most existing methods consider the effect of post‐tensioning the rock bolt or anchor after the grout has set. Tennessee Department of Transportation (TDOT) has successfully utilized this method in the past, but the typical design method based on the pure shear capacity of the dowel fails to consider the effect of rock joint thickness, which introduces bending to the dowel.
