• If a linear analysis is performed using the stiffness at zero, the full axial stiffness (AE/L) of the element will be used as if there were no limits.

• If a linear analysis is performed using the stiffness at the end of a nonlinear analysis, the axial stiffness will be zero (more precisely, when tension/compression limits are used, the program replaces the behavior with a very soft spring (1e-6*EA/L)) or AE/L, depending on whether the object exceeded its limits at the end of the nonlinear case.
