Lateral Torsional Buckling vs Torsion

A graphical user interface of structural analysis software showing a torsion beam model with mesh elements. The display includes a workspace on the left, a properties pane on the right, and a 3D view of the beam in the center with displacement results for a load case.

One of the most challenging aspects of structural design, in my opinion, is ensuring that all relevant checks are accounted for. How many checks are necessary to confirm that a structural member can safely resist the imposed loads? The type of loads and their resulting effects often guide this process. For example, a member subjected […]

Understanding Torsion – Part 01

A deformed view of an I-beam under torsional loading displayed in structural analysis software. The beam shows significant warping and displacement along the cross-section edges, with numerical values of maximum displacements annotated.

To kick of this series, please read our blog: Difference Between Lateral Torsional Buckling & Torsion. Torsion has proven to be more complex than many initially assume. Not only does it manifest in distinct forms—St. Venant torsion and Warping torsion—but it also introduces various load effects, including axial, shear, and bending stresses. Adding to this […]
