Lateral torsional buckling and how to counter

Question

Accepted Answer

Lateral torsional buckling is a phenomenon in which a beam undergoes both lateral deflection and twisting under load, potentially leading to structural failure.

Lateral torsional buckling can be countered by increasing the beam's stiffness through the use of larger sections or adding lateral bracing.
Designing the beam with a more compact shape can also help prevent lateral torsional buckling.
Using materials with higher yield strength can increase the beam's resistance to lateral torsional buckling.
Properly calculating the critical buckling load and ensuring the applied load does not exceed this limit is crucial in preventing lateral torsional buckling.
For example, in a steel beam design, adding stiffeners or increasing the flange width can help counter lateral torsional buckling.
