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.
| uniaxialMaterial AxialSpHD $matTag $sce $fty $fcy <$bte $bty $bth $bcy $fcr $ath> |
| $matTag | integer tag identifying material |
| $sce | compressive modulus |
| $fty $fcy | yield stress under tension ($fty) and compression ($fcy) (see note 1) |
| $bte $bty $bth $bcy | reduction rate for tensile elastic range ($bte), tensile yielding ($bty), tensile hardening ($bth) and compressive yielding ($bcy) (see note 1) |

NOTES:
1) Input parameters are required to satisfy followings.
