Influence of the distortional-lateral buckling mode on the interactive buckling of short channels

Thin-Walled Structures, 2016
Abstract The present paper deals with an influence of the distortional-lateral buckling mode on the interactive buckling of thin-walled short channels with imperfections subjected to the bending moment when the shear lag phenomenon and distortional deformations are taken into account. A plate model (2D) is adopted for the channel section.

Lateral distortional buckling in steel-concrete composite beams: A review

Structures, 2020
Abstract Steel-concrete composite beams, when requested by negative moment, can fail due to Lateral Distortional Buckling (LDB), local buckling, by a combination of these stability modes or achieve the plastic behavior. LDB is a mode of stability in which the web must distort in order for the compression flange to displace and twist during buckling ...

Distortional lateral torsional buckling of beam-columns including pre-buckling deformation effects

Computers and Structures, 2018
Abstract The present study develops a unified distortional lateral torsional buckling finite element formulation for the elastic analysis of beam-columns with wide flange doubly symmetric cross-sections. The solution captures several non-conventional features including the softening effect due to web distortion, the stiffening effect induced by pre ...

Assessment of lateral distortional buckling resistance in welded I-beams

Journal of Constructional Steel Research, 2020
Abstract Lateral distortional buckling (LDB) of I-beams is characterized by simultaneous lateral deflection, twist and cross section change due to web distortion. The present study investigates the effect of web distortion in LDB resistance of doubly-symmetric welded I-beams.

Numerical assessment of lateral distortional buckling in steel-concrete composite beams

Journal of Constructional Steel Research, 2020
Abstract Steel-concrete composite beams, when requested by negative moment, can fail due to Lateral Distortional Buckling (LDB), local buckling, or by the combination of these stability modes. LDB is a mode of stability in which the web must distort in order for the compression flange to displace and twist during buckling.
