uniaxialMaterial command

Hi,

using the uniaxialMaterial Command one can define a stress-strain relation or a force-deformation relation.

Is there a chance to define a moment-curvature relation??

Thanks,
Andreas

You should define your uniaxial materials considering what you're going to assign them to. If it's going to represent a section of a nonlinearBeamColumn element, then the uniaxialMaterial should define a moment-curvature relationship. If it's going to be assigned to a zero length element (say a rotational spring), then it should define a moment-rotation relationship. Similarly, if it's going to be assigned to a fiber in a fiber section, then it should define a stress-strain relationship...
