220.127.116.11. PySimple1 Material¶
uniaxialMaterial('PySimple1', matTag, soilType, pult, Y50, Cd, c=0.0)
This command is used to construct a PySimple1 uniaxial material object.
integer tag identifying material
soilType = 1 Backbone of p-y curve approximates Matlock (1970) soft clay relation.
soilType = 2 Backbone of p-y curve approximates API (1993) sand relation.
Ultimate capacity of the p-y material. Note that “p” or “pult” are distributed loads [force per length of pile] in common design equations, but are both loads for this uniaxialMaterial [i.e., distributed load times the tributary length of the pile].
Displacement at which 50% of pult is mobilized in monotonic loading.
Variable that sets the drag resistance within a fully-mobilized gap as Cd*pult.
The viscous damping term (dashpot) on the far-field (elastic) component of the displacement rate (velocity). (optional Default = 0.0). Nonzero c values are used to represent radiation damping effects
