Parameter Default Value Description
CMZ 0.85 Cm value in local Z axis. Used
in the interaction equations in
Chapter H of AISC
specifications.
TRACK 0 Parameter used to control the
level of description of design
output. Permissible values are 0
and 1 .
RATIO 1.0 Permissible maximum ratio of
actual load to section capacity.
Any input value will be used to
change the right hand side of
governing interaction equations
in Chapter H and elsewhere.

Cross-section checks:
The first check that is carried out is a verification whether the
member properties satisfy certain basic requirements. If the
