The name of the pile-soil interaction coefficients/curves.(PSIC)
Curve
For each PSIC, the coefficient is a function of , is normalised relative displacement, i.e. . , & are explained in Pile-soil interaction property table. If is outside the defined range on positive or negative side of PSIC curve, the last value on positive or negative side of the curve will be used as the corresponding value, i.e. the curve is extended horizontally on both positive and negative sides.
