Steel Column Design Settings are explained in detail under this title.
Design Settings Sub-Tabs
After completing the steel column modeling is completed, double-click on the element to enter its properties.
...
Two new sub-tabs, “Releases / Partial Fixity” and “Design,”will appear in the steel column setting menu. These tabs contain adjustments for analysis and design.
...
Override end releases  This command is activated by defining user-defined end releases. |
I-Release  If the axial force for the starting point of the element 2-direction shear force, 3-direction shear force, torsion, 2-direction moment, and 3-direction moment are indicated, the corresponding force will be 0 at the starting point. |
J-Release  For the end point endpoint of the element, axial force, 2-direction shear force, 3-direction shear force, torsion, 2-direction moment, and 3-direction moment are indicated, and the corresponding force will be 0 at the starting end. |
Spring values - I  The spring coefficient is entered for the starting point of the element. Units can be changed by clicking the right button in the box. |
Spring values - J  Spring The spring coefficient is entered for the end point endpoint of the element. Units can be changed by clicking the right button in the box. |

Effective length factor (K Major)  Effective length factor for major axis. |
Effective length factor (K Minor)  Effective length factor for minor axis |
Unbraced length ratio (Major)  The ratio of the length between two elements connected to the element in its strong direction to the entire element length |
Unbraced length ratio (Minor)  The ratio of the length between two elements connected in the weak direction to the entire element length |
Unbraced length ratio (LTB)  The ratio of the length between laterally unbraced length along either flange |
Bending Coefficient (Cb)  Lateral-torsional buckling modification factor for nonuniform moment diagrams when both segment ends of the segment are braced. It’s determined according to AISC 360-16 F1-1. |
