Torque VS Capacity

  • The relationship between torque applied during anchor installation and the installed anchor’s load capacity
  • The torque versus anchor capacity method was used to verify the load capacity at installation.
  • This method multiplies the effective torsional resistance encountered during installation of the helical anchor by an empirical factor to determine the compression load limit or pullout resistance of the anchor
  • Empirical Torque Factor is related to friction during installation and is impacted by shaft size and shape, soil properties, and number and size of helix plates.
