4.13.5.30. AxialSp Material

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

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
