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).
matTag
(int)integer tag identifying material fpc
(float)concrete compressive strength at 28 days (compression is negative) epsc0
(float)concrete strain at maximum strength fpcu
(float)concrete crushing strength epsU
(float)concrete strain at crushing strength
Note
- 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)
