This iss used primarily to mod del tension‐‐only cabless and brace es. The behavio or modeled is nonlineaar but elastic. For exam mple, assume a compreession limit o of zero has beeen set. If thee object triees to go into o axial comp pression, it will shorten n without any stiffness.

If a linear analysis is performeed using thee stiffness at zero, the ffull axial stiffness (AE/L) of the elemen nt will be used as if there were no limits.
