where,
i
1
= Maximum number of primary load cases (NL)
i
2
= Maximum allowable displacement tolerance for any joint in
the structure.
i
3
= Damping ratio to be used for all springs in computing the
modal composite damping in dynamics.
i
4
= Warping restraint ratio to be used for I section members in
computing the torsional rigidity. If 0.0 then no warping
restraint, normal default option; If 1.0 then full warping
restraint. Cw, the warping constant, will be computed and
used in the torsional rigidity calculation. Values between 0.0
and 1.0 will result in a partial warping restraint.
i
5
= Maximum number of tension/compression iterations.
i
6
= 1, Bypass forming data and files needed for post-processing.
i
7
= 1, Bypass printing Zero Stiffness messages.
