This does not apply to AISC 360, the command is not available when that code is selected. With the Criteria - K-Factor command, Kx and Ky values are set for the beams, columns and braces in the structure . For columns, the K-Factor can be calculated by the program using Nomograph values or can be specified by the engineer.

Modifying the K-Factor criteria after a Code Check has been performed will invalidate the results of that Code Check. The model will be redrawn on the screen in its original colors (rather than the Code Check colors) indicating that the Code Check must be re-run.

Refer to the Assign chapter for information on how this criterion can be overridden on a member-by-member basis.
