4.14.5.31. AxialSpHD MaterialΒΆ
- 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.
matTag
(int)integer tag identifying material
sce
(float)compressive modulus
fty
fcy
(float)yield stress under tension (
fty
) and compression (fcy
) (see note 1)bte
bty
bth
bcy
(float)reduction rate for tensile elastic range (
bte
), tensile yielding (bty
), tensile hardening (bth
) and compressive yielding (bcy
) (see note 1)fcr
(float)target point stress (see note 1)
ath
(float)hardening strain ratio to yield strain
Note
Input parameters are required to satisfy followings.
