Steel01

Description

The Steel01 material model is a one-dimensional model of bilinear hysteretic response that can be used anywhere a UniaxialMaterial is expected in OpenSees. Although its name refers to steel, the Steel01 model can be used anywhere one-dimensional bilinear response is desired, e.g., in spring and link elements, not just in fibers of steel sections.

Syntax

ops.uniaxialMaterial('Steel01',tag,Fy,E,b)
ops.uniaxialMaterial('Steel01',tag,Fy,E,b,a1,a2,a3,a4)

Parameters

• tag : integer Unique material identifier
• Fy : float Initial yield stress
• E : float Elastic modulus
• b : float Kinematic strain hardening ratio

Optional Parameters

• a1–a4 : float Isotropic hardening parameters

Notes

None

Examples

ops.uniaxialMaterial('Steel01',1,50,29000,0.005)
