Cable Bolts

The Cable Bolt type can be used to model fully bonded cable bolts with face plates, or any similar type of bolt.

 Cable Bolt

Fully bonded cable bolt with face plate

The implementation of the Cable Bolt model in UnWedge is exactly the same as the Grouted Dowel model, except that the Bonded Length for a Cable Bolt is always 100%. For a Grouted Dowel, the bolt does not have to be fully bonded, the user may specify a Bonded Length less than 100%.

Except for this difference, the implementation and parameters of the Cable Bolt and Grouted Dowel models are identical in UnWedge. For complete details, please see the Grouted Dowel topic.

Bolt Force Diagram

A Force diagram for a Cable Bolt, which exhibits all three failure modes, is shown below. In this case, the Plate Capacity is less than the Tensile Capacity, and therefore "stripping" is a possible failure mode. If the Plate Capacity is greater than the Tensile Capacity, then stripping cannot occur, and the Force diagram will be determined only by the Tensile and Pullout failure modes.
