4.13.2.4. Concrete06

uniaxialMaterial('Concrete06', matTag, fc, e0, n, k, alpha1, fcr, ecr, b, alpha2)

This command is used to construct a uniaxial concrete material object with tensile strength, nonlinear tension stiffening and compressive behavior based on Thorenfeldt curve.

matTag (int)	integer tag identifying material
fc (float)	concrete compressive strength (compression is negative)
e0 (float)	strain at compressive strength
n (float)	compressive shape factor
k (float)	post-peak compressive shape factor
alpha1 (float)	\(\alpha_1\) parameter for compressive plastic strain definition
fcr (float)	tensile strength
ecr (float)	tensile strain at peak stress (fcr)
b (float)	exponent of the tension stiffening curve
alpha2 (float)	\(\alpha_2\) parameter for tensile plastic strain definition

Note

1. Compressive concrete parameters should be input as negative values.
