220.127.116.11. TzSimple1 Material¶
uniaxialMaterial('TzSimple1', matTag, soilType, tult, z50, c=0.0)
This command is used to construct a TzSimple1 uniaxial material object.
integer tag identifying material
soilType = 1 Backbone of t-z curve approximates Reese and O’Neill (1987).
soilType = 2 Backbone of t-z curve approximates Mosher (1984) relation.
Ultimate capacity of the t-z material. SEE NOTE 1.
Displacement at which 50% of tult is mobilized in monotonic loading.
The viscous damping term (dashpot) on the far-field (elastic) component of the displacement rate (velocity). (optional Default = 0.0). See NOTE 2.
- The argument tult is the ultimate capacity of the t-z material. Note that “t” or “tult” are shear stresses [force per unit area of pile surface] in common design equations, but are both loads for this uniaxialMaterial [i.e., shear stress times the tributary area of the pile].
- Nonzero c values are used to represent radiation damping effects
