This command is used to construct a uniaxial concrete material object with tensile strength and linear tension softening. This is a Fedeas Material and the source code may not be available, yet.
uniaxialMaterial Concrete02 $matTag $fpc $epsc0 $fpcu $epscu $lambda $ft $Ets
$matTag |
unique material object integer tag |
$fpc |
compressive strength* |
$epsc0 |
strain at compressive strength* |
$fpcu |
crushing strength* |
$epsU |
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)
