| Bolt Pattern Group Pullout Excel Spreadsheet Calculator |
| This design uses the anchor bolt to clamp the steel baseplate down onto the concrete slab/foundation. After grouting beneath the base plate, the bolt is tensioned by tightening the nut -- usually about 1/4 turn of the nut.
Lateral loads are converted to bolt tension loads via the concept of shear friction. Bolt lateral capability is factored down with the factors λ and µ which account for a steel plate trying to slide on concrete.
