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.

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 ...

Lateral–distortional buckling of I-beams and the extrapolation techniques

Journal of Constructional Steel Research, 2008
Abstract Various extrapolation techniques are utilized for predicting the critical buckling load of structural members undergoing lateral buckling. For the application of these methods it is only necessary to have data relating load to a deformation characteristic.

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 ...

A unified analysis for distortional and lateral buckling of C-purlins in flexure

Thin-Walled Structures, 2015
Abstract This paper developed a unified model for the distortional and lateral buckling of cold-formed C-purlins subjected to bending in the plane of symmetry. It can study not only the distortional buckling, but also the global lateral buckling.

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.

An Analytical Solution for the Elastic Lateral-Distortional Buckling of I-section Beams

Advances in Structural Engineering, 2004
Lateral-distortional buckling may occur in I-section beams with slender webs and stocky flanges. A computationally efficient method is presented in this paper to study this phenomenon. Previous studies on distortional buckling have been on the use of 3 rd and 5 th

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.

Lateral-Distortional Buckling of Hollow Flange Beams

Journal of Structural Engineering, 1997
While the flanges of cold-formed hollow flange beams (HFBs) are very stiff torsionally, their webs are comparatively flexible, and may allow web distortion effects to reduce their resistances to lateral buckling. There is no simple formulation for predicting the effects of web distortion on the lateral buckling of HFBs.
