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 calculation. If no mark is placed in the box, the program automatically calculates these coefficients and uses them in the design.

| Bracketed Laterally unbraced length ratio (LTB) | The ratio of the length between two elements connected to the element for the respective direction to the entire element length to be used in the lateral torsion buckling calculationFlexural coefficient laterally unbraced length along either flange |
The lateral-torsional buckling modification factor (Cb) | The moment correction coefficient is calculated according to the Steel Structures Regulation Equation 9.Lateral-torsional buckling modification factor for nonuniform moment |
Deflection borderlimit | It is the elementmember-based limit value specified in the relevant Steel Structures regulation used in the design. The program does not automatically change the limit such as cantilever beams. The limit value must be changed by the user according to the situations where the secondary beam is used. |
The control check is given in the steel design - golden secondary beam - details section after analysis and design.
