AB  - The lateral-torsion buckling modification factor, C<SUB>b,</SUB> for Universal Columns in BS 5950 was investigated in order to determine its safety in frames braced against joint translation. These columns were evaluated based on the AISC specification for structural steel buildings. Results indicate that the modification factor C<SUB>b</SUB> varied extensively with the end moment ratios and with associated safety values and column heights (1-7 m) of frames braced against joint translation. The C<SUB>b</SUB> values that can be used depending on the steel section, end moment ratios and column heights are also predicted.
