Steel beams at risk of failure due to lateral torsional buckling.
Lateral torsional buckling is a critical issue for steel beams, where they can fail before reaching their full strength if not properly supported. This study looked at how I-shaped steel beams buckle laterally when loaded and twisted, using different methods like design standards and computer simulations. The results showed that lateral torsional buckling is a big problem for these beams, especially when they are bent, but current design codes are doing a good job of keeping them safe.
