This command is used to construct a uniaxial Kent-Scott-Park concrete material object with degraded linear unloading/reloading stiffness according to the work of Karsan-Jirsa and no tensile strength. (REF: Fedeas).
| uniaxialMaterial Concrete01 $matTag $fpc $epsc0 $fpcu $epsU |
| $matTag | integer tag identifying material |
| $fpc | concrete compressive strength at 28 days (compression is negative)* |
| $epsc0 | concrete strain at maximum strength* |
| $fpcu | concrete crushing strength * |
| $epsU | concrete strain at crushing strength* |
NOTE:
- Compressive concrete parameters should be input as negative values (if input as positive, they will be converted to negative internally).
- The initial slope for this model is (2*$fpc/$epsc0)
Typical Hysteretic Stress-Strain Relation for material
EXAMPLE:
uniaxialMaterial Concrete01 1 -4.0 -0.002 0.0 -0.005; # the concrete material with tag 1 reaches compressive strength of 4.0 at strain of 0.002 and reaches ultimate strength of 0.0 at strain of 0.005.
