This command is used to construct a uniaxialMaterial model that simulates the hysteresis response (Shear strength-lateral Displacement) of a steel sheathed Cold-Formed Steel Shear Wall Panel. The hysteresis model has smooth curves and takes into account the strength and stiffness degradation, as well as pinching effect.
