As per IS 800: 2007 (General Construction in Steel — Code of Practice):
-
Lateral Torsional Buckling (LTB) is a stability concern primarily for open sections (like I-beams) when bending about their major axis and the compression flange is unrestrained.
-
Hollow rectangular or tubular sections are closed shapes and geometrically stable in torsion.
- Their symmetry and enclosed shape resist both lateral displacement and twisting, making LTB checks generally unnecessary.
Additional Information
- Plate girders: Require LTB checks, especially due to their large depth and slenderness.
- Beams bending about their major axis with λLT more than 0.4: Higher slenderness ratio indicates potential for buckling; LTB check is required.
- I-section beams with a long span: More susceptible to LTB due to unrestrained compression flange over long lengths.
