This command is used to construct a uniaxial AxialSp material object. This material model produces axial stress-strain curve of elastomeric bearings.
| uniaxialMaterial AxialSp $matTag $sce $fty $fcy <$bte $bty $bcy $fcr> |
| $matTag | integer tag identifying material |
| $sce | compressive modulus |
| $fty $fcy | yield stress under tension ($fty) and compression ($fcy) (see note 1) |
| $bte $bty $bcy | reduction rate for tensile elastic range ($bte), tensile yielding ($bty) and compressive yielding ($bcy) (see note 1) |
| $fcr | target point stress (see note 1) |
NOTES:
1) Input parameters are required to satisfy followings.
$fcy < 0.0 < $fty
0.0 <= $bty < $bte <= 1.0
0.0 <= $bcy <= 1.0
$fcy <= $fcr <= 0.0
