uniaxialMaterial
('ConcreteD', matTag, fc, epsc, ft, epst, Ec, alphac, alphat, cesp=0.25, etap=1.15) This command is used to construct a concrete material based on the Chinese design code.
matTag
(int)integer tag identifying material fc
(float)concrete compressive strength epsc
(float)concrete strain at corresponding to compressive strength ft
(float)concrete tensile strength epst
(float)concrete strain at corresponding to tensile strength Ec
(float)concrete initial Elastic modulus alphac
(float)compressive descending parameter alphat
(float)tensile descending parameter cesp
(float)plastic parameter, recommended values: 0.2~0.3 etap
(float)plastic parameter, recommended values: 1.0~1.3
Note
- Concrete compressive strength and the corresponding strain should be input as negative values.
- The value
fc/epsc
andft/epst
should be smaller thanEc
.
