AxialSpHD Material
From OpenSeesWiki
Jump to navigationJump to search
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) |
$fcr | target point stress (see note 1) |
$ath | hardening strain ratio to yield strain (see note 1) |
NOTES:
1) Input parameters are required to satisfy followings.
$fcy < 0.0 < $fty
0.0 <= $bty < $bth < $bte <= 1.0
0.0 <= $bcy <= 1.0
$fcy <= $fcr <= 0.0
1.0 <= $ath
