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 3rd and 5th order polynomials to model the displacements.

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 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.

Lateral and distortional buckling of pultruded I-beams

Composite Structures, 1994
Abstract The elastic buckling modes of pultruded I-beams subjected to various loading conditions are studied. The coupling of lateral and distortional buckling, very likely to appear in thin-walled cross-sections, is investigated. Plate theory is used to allow for distortion of the cross-section.

Lateral-distortional buckling of continuously restrained columns

Journal of Constructional Steel Research, 1997
Abstract A rational model for predicting the elastic buckling load of thin-walled Isection columns, restrained fully against translation and elastically against twist at one flange, is presented. The energy method used results in a third-order eigenproblem.

Lateral, local and distortional buckling of I-beams

Thin-Walled Structures, 1983
Abstract A theoretical study of the elastic buckling modes of I-section beams under various loading conditions is presented. The analysis is based on energy considerations and the energy equations governing instability are derived using plate theory to allow for distortion of the cross-section.

DISTORTIONAL LATERAL BUCKLING OF CONTINUOUS COMPOSITE BEAMS.

Proceedings of the Institution of Civil Engineers, 1991
Lateral buckling of continuous composite beams can occur only in a distortional mode, and is most unlikely in practical building or bridge structures of span up to about 35 m. Designers need simpler and less conservative methods of checking resistance to buckling. Recent theories, and current and proposed methods are summarized.

Lateral–distortional buckling of monorails

Engineering Structures, 2009
Abstract This paper is concerned with the elastic lateral–distortional (LD) buckling of single span steel monorail I-beams and its influence on their design strengths. The distortion of a slender web reduces the elastic buckling resistance of an intermediate length beam below its flexural–torsional (FT) resistance.

Lateral Distortional Buckling: Predicting Elastic Critical Stress

Journal of Structural Engineering, 1988
The problem of restrained lateral beam buckling is being treated in this paper. The restraint represents complete lateral and arbitrary continuous rotational restraint of one flange, the latter is represented by the spring stiffness \IC\N\d0. A simple theory, in which the problem is transformed into an ordinary fourth order differential eigenvalue ...
