This command is used to construct a uniaxial concrete material object with tensile strength and nonlinear tension softening. This is a Fedeas Material and the source code may not be available, yet.
uniaxialMaterial Concrete03 $matTag $fpc $epsc0 $fpcu $epscu $lambda $ft $epst0 $ft0 $beta $epstu
$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 $epscu and initial slope (=2*$fpc/$epsc0) |
$ft |
tensile strength |
$epst0 |
tensile strain at the transition from nonlinear to linear softening |
$ft0 |
