4.14.4.2. TzSimple1 Material¶
-
uniaxialMaterial
('TzSimple1', matTag, soilType, tult, z50, c=0.0) This command is used to construct a TzSimple1 uniaxial material object.
matTag
(int)integer tag identifying material soilType
(int)soilType = 1 Backbone of t-z curve approximates Reese and O’Neill (1987).
soilType = 2 Backbone of t-z curve approximates Mosher (1984) relation.
tult
(float)Ultimate capacity of the t-z material. SEE NOTE 1. z50
(float)Displacement at which 50% of tult is mobilized in monotonic loading. c
(float)The viscous damping term (dashpot) on the far-field (elastic) component of the displacement rate (velocity). (optional Default = 0.0). See NOTE 2.
Note
- The argument
tult
is the ultimate capacity of the t-z material. Note thatt
ortult
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
