4.14.5.30. AxialSp MaterialΒΆ
-
uniaxialMaterial
('AxialSp', matTag, sce, fty, fcy, <bte, bty, bcy, fcr>) This command is used to construct a uniaxial AxialSp material object. This material model produces axial stress-strain curve of elastomeric bearings.
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
bcy
(float)reduction rate for tensile elastic range ( bte
), tensile yielding (bty
) and compressive yielding (bcy
) (see note 1)fcr
(float)target point stress (see note 1)
Note
Input parameters are required to satisfy followings.
