| EFu | EFu | The expected tensile stress. MPa | Number |
| Set by Weight | W | Set the Material by Weight Density, rather than Mass Density | Boolean |
| Weight | W | The Weight of the material kN/m3 | Number |
| SS Curve Type | SC | The stress-strain curve type: (0=User_Defined 1=Parametric_Simple 2=Parametric_Park) | Integer |
| HysS Curve Type | SC | The stress-strain hysteresis type: (0=Elastic 1=Kinematic 2=Takeda 3=Pivot 4=Concrete 5=BRB_Hardening 6=Degrading 7=Isotropic) | Integer |
| Strain at Hardening | H | This item applies only when parametric stress-strain curves are used and when UseCaltransSSDefaults is False. It is the strain at the onset of strain hardening | Number |
| Strain at Max Stress | S | This item applies only when parametric stress-strain curves are used and when UseCaltransSSDefaults is False. It is the ultimate strain capacity. This item must be larger than the StrainAtHardening item | Number |
| Strain at Rupture | R | This item applies only when parametric stress-strain curves are used and when UseCaltransSSDefaults is False. It is the ultimate strain capacity. This item must be larger than the StrainAtHardening item | Number |
| Final Slope | S | This item applies only to parametric stress-strain curves. It is a multiplier on the material modulus of elasticity, E. This value multiplied times E gives the final slope of the curve. | Number |
