SmoothPSConcrete

This command is used to construct a uniaxial smoothed Popovics-Saenz concrete material object.

uniaxialMaterial SmoothPSConcrete $matTag $fc $fu $Ec
        $epso $epsu $eta

matTag

unique material object integer tag

fc

concrete compressive strength (positive for compression)

fu

concrete crushing strength (positive for compression

Ec

initial tangent stiffness

epsco

concrete strain at maximum strength (positive for compression)

epsu

concrete strain at crushing strength (positive for compression)

eta

smoothing parameter (default value = 0.2).

Note: For this material class, the sensitivity parameters can be: fc, fu, Ec, epsco, epscu, eta
