uniaxialMaterial Concrete02 $matTag $fpc $epsc0 $fpcu $epsU $lambda $ft $Ets |
$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* |
$lambda | ratio between unloading slope at $epscu and initial slope |
$ft | tensile strength |
$Ets | tension softening stiffness (absolute value) (slope of the linear tension softening branch) |
NOTE:
- Compressive concrete parameters should be input as negative values.
- The initial slope for this model is (2*$fpc/$epsc0)
