uniaxialMaterial('ECC01', matTag, sigt0, epst0, sigt1, epst1, epst2, sigc0, epsc0, epsc1, alphaT1, alphaT2, alphaC, alphaCU, betaT, betaC)

This command is used to construct a uniaxial Engineered Cementitious Composites (ECC)material object based on the ECC material model of Han, et al. (see references). Reloading in tension and compression is linear.

matTag (int)

integer tag identifying material

sigt0 (float)

tensile cracking stress

epst0 (float)

strain at tensile cracking stress

sigt1 (float)

peak tensile stress

epst1 (float)

strain at peak tensile stress

epst2 (float)

ultimate tensile strain

sigc0 (float)

compressive strength (see NOTES)

epsc0 (float)

strain at compressive strength (see NOTES)

epsc1 (float)

ultimate compressive strain (see NOTES)

alphaT1 (float)

exponent of the unloading curve in tensile strain hardening region

alphaT2 (float)

exponent of the unloading curve in tensile softening region

alphaC (float)

exponent of the unloading curve in the compressive softening

alphaCU (float)

exponent of the compressive softening curve (use 1 for linear softening)

betaT (float)

parameter to determine permanent strain in tension

betaC (float)

parameter to determine permanent strain in compression
