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)


  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
