Steel Column Design Settings are explained in detail under this title.
Design Settings Sub-Tabs
After the steel column modeling is completed, double-click on the element to enter its properties.
...
Two new sub-tabs will appear in the steel column setting menu. These tabs contain adjustments for analysis and design.
Releases / Partial Fixity
In the Releases tab, end releases and spring values can be entered at the starting and ending points of the element.
...
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 of the element, axial force, 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 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 coefficient is entered for the end point of the element. Units can be changed by clicking the right button in the box. |
Design
The parameters used in the design are intervened in the Design tab. If a mark is placed in the box, the coefficient written in the box is used in the design. If no mark is placed in the box, ideCAD Structural automatically determines these coefficients and uses them in the design.
...
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 |
Laterally unbraced Unbraced length ratio (LTB)  The ratio of the length between laterally unbraced length along either flange |
The lateral-torsional buckling modification factor Bending Coefficient (Cb)  Lateral-torsional buckling modification factor for nonuniform moment diagrams when both ends of the segment are braced. It’s determined according to AISC 360-16 F1-1. |
Control After analysis and design, the design check window is given in the steel design - column - details section after analysis and design“Column design → Column details” section.
