CAESAR II Version

Specifies the soil stiffness in the downward direction on a stiffness per length basis. The value that you enter is the stiffness that will resist downward (-Y) displacement of the pipeline. This option is required if Soil Model No. is set to 1; otherwise, you can leave this option blank.

The smallest allowable non-zero value is 0.5.

  • If the upward and downward stiffnesses are equal, then you need only enter a value for one. The other stiffness defaults to the entered value.

  • If both User-Defined Upward Stif and User-Defined Downward Stif are set to 0 or left blank, the software returns a fatal error.
