Concrete02 Material -- Linear Tension Softening
|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 $epscu and initial slope|
|$Ets||tension softening stiffness (absolute value) (slope of the linear tension softening branch)|
- Compressive concrete parameters should be input as negative values.
- The initial slope for this model is (2*$fpc/$epsc0)
