Older versions of the column modules only had the Column Slenderness tab input to take some sort of guess as to what the bracing condition is for defining the lateral-torsional buckling strength.  But there may be times where the bracing that is effective in resisting Euler (column) buckling would not be considered as effective in resisting lateral-torsional buckling.  So the Beam Stability tab allows the user to more effectively define the column and the bracing for all of its failure modes. 

 

In the Wood Column module, the program evaluates the dimensions of the column member and offers an input for the unbraced length to apply when evaluating flexure about the strong axis of the member.

 

The tab for the weak axis simply indicates that lateral-torsional buckling is not a consideration when flexure occurs about the weak axis.
