Lateral-torsional buckling of compressed and highly variable cross section beams

Curved and Layered Structures, 2016
In the critical state of a beam under central compression a flexural-torsional equilibrium shape becomes possible in addition to the fundamental straight equilibrium shape and the Euler bending.

The effect of residual stresses in the lateral-torsional buckling of steel I-beams at elevated temperature [PDF]

, 2004
When a beam is bent about its major axis, it may twist and move laterally, before it reaches its elastic/plastic resistance in bending. Although the problem of lateral-torsional buckling of steel beams at room temperature has a well-established solution,

Span-dependent comparative analysis of lateral torsional buckling and nonlinear load behaviour in castellated and solid I-beams using analytical and finite element approaches

Materials Research Express
Castellated beams (CB), widely employed in modern construction, offer an improved strength-to-weight ratio and enhanced structural efficiency due to their increased depth and moment of inertia.

A simple model for lateral torsional buckling resistance of steel I beams under fire condition – comparison with experimental results [PDF]

, 2010
When a beam is bent about its axis of greatest flexural rigidity it may twist before it reaches its strength limit state. This flexural stability limit state is most commonly referred to as lateral torsional buckling of a beam. The twisting of the beam
