The Effect of Steel Beam Elastic Restraint on the Critical Moment of Lateral Torsional Buckling [PDF]

Materials, 2022
This paper reports the results of the next stage of the authors’ investigations into the effect of the elastic action of support nodes on the lateral torsional buckling of steel beams with a bisymmetric I-section.

Closed-form approach for the elastic critical moment of I-girders with corrugated web [PDF]

Thin-Walled Structures
Using corrugated web girders offers several advantages, including increased resistance to lateral-torsional buckling. Researchers have proposed various methods for determining the critical moment value as a function of the cross-sectional geometry ...

On the evaluation of elastic critical moments in doubly and singly symmetric I-section cantilevers [PDF]

Journal of Constructional Steel Research, 2007
The so-called 3-factor formula is one of the most commonly employed general formulae to estimate the elastic critical moment of steel beams prone to lateral-torsional buckling. This work extends its domain of application to I-section cantilevers (i) with

Elastic critical moment of beams with sinusoidally corrugated webs

Journal of Constructional Steel Research, 2017
Abstract This paper approaches the elastic critical moment of web-corrugated beams (WCB), either subjected to a uniform bending moment, gradient bending moments, or a uniformly distributed load. Previous research on the subject of lateral-torsional buckling (LTB) of WCB is presented and critically reviewed.
