The following options are available for MSF:

  • None
  • Tokimatsu and Seed (1987)
  • Idriss (1999)
  • Andrus Stokoe (1997)
  • Idriss and Boulanger (2008)
  • Idriss (NCEER)

Rd is the shear stress reduction coefficient, and is used to determine the maximum shear stress at different depths. Typically, values range from 1 at the ground surface to lower values at greater depths.

The following calculation methods are available for Rd:

  • NCEER (1997)
  • Idriss (1999)
  • Kayen (1992)
