18.104.22.168. AxialSpHD Material¶
uniaxialMaterial('AxialSpHD', matTag, sce, fty, fcy, <bte, bty, bth, bcy, fcr, ath>)
This command is used to construct a uniaxial AxialSpHD material object. This material model produces axial stress-strain curve of elastomeric bearings including hardening behavior.
integer tag identifying material
yield stress under tension (
fty) and compression (
fcy) (see note 1)
reduction rate for tensile elastic range (
bte), tensile yielding (
bty), tensile hardening (
bth) and compressive yielding (
bcy) (see note 1)
target point stress (see note 1)
hardening strain ratio to yield strain
Input parameters are required to satisfy followings.
