AxialSp

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
