uniaxialMaterial('Concrete01', matTag, fpc, epsc0, fpcu, epsU)
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).
integer tag identifying material
concrete compressive strength at 28 days (compression is negative)
concrete strain at maximum strength
concrete crushing strength
concrete strain at crushing strength
- 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)
