*PIPE-SOIL STIFFNESS
3. Temperature.
4. First field variable.
5. Second field variable.
6. Etc., up to five field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than five):
1. Sixth field variable.
2. Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the force per unit length as a function of
relative displacement, temperature, and other predefined field variables.
Data lines to define constitutive behavior using the ASCE formula for sand in the axial direction
(TYPE=SAND, DIRECTION=AXIAL):
First line:
1. Effective unit weight of soil, .
2. Coefficient of soil pressure at rest, .
3. Interface angle of friction, . Give the value in degrees.
4. External pipe diameter, D.
5. Ultimate relative displacement, .
6. Temperature.
7. First field variable.
8. Second field variable.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than two):
1. Third field variable.
2. Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the parameters for the ASCE formulae as a
function of temperature and other predefined field variables.
Data lines to define constitutive behavior using the ASCE formula for clay in the axial direction
(TYPE=CLAY, DIRECTION=AXIAL):
First line:
1. Undrained soil shear strength, S.
2. Empirical adhesion factor, .
3. External pipe diameter, D.
4. Ultimate relative displacement, .
5. Temperature.
6. First field variable.
