Numerical assessment of lateral distortional buckling in steel-concrete composite beams
Journal of Constructional Steel Research, 2020Abstract 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.

Lateral distortional buckling tests of a new hollow flange channel beam
Thin-Walled Structures, 2011 The LiteSteel beam (LSB) is a new hollow flange channel section developed by OneSteel Australian Tube Mills using their patented dual electric resistance welding and automated continuous roll-forming process. It has a unique geometry consisting of torsionally rigid rectangular hollow flanges and a relatively slender web.

Lateral–distortional buckling of monorails
Engineering Structures, 2009Abstract 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.

A unified analysis for distortional and lateral buckling of C-purlins in flexure
Thin-Walled Structures, 2015Abstract 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.

An Analytical Solution for the Elastic Lateral-Distortional Buckling of I-section Beams
Advances in Structural Engineering, 2004Lateral-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

Lateral Distortional Buckling: Predicting Elastic Critical Stress
Journal of Structural Engineering, 1988The 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 ...

ELASTIC LATERAL AND RESTRAINED DISTORTIONAL BUCKLING OF DOUBLY SYMMETRIC I-BEAMS
International Journal of Structural Stability and Dynamics, 2010Based on the energy principle, a theoretical study of the elastic lateral distortional buckling (LDB) and restrained distortional buckling (RDB) of I-beams is presented. First, because the existing potential energy expressions for LDB are not suitable for members under a transverse distributed load, a new general potential energy expression of I-beams ...

Lateral-distortional buckling of tee-section beams
Thin-Walled Structures, 1990Abstract A fine element method that incorporates plate behaviour is developed for modelling the lateral-distortional buckling of tee-section beams. The method is shown to agree well with independent buckling results for tee-beams. Since relatively few elements are needed to obtain satisfactory convergence, the method is efficient computationally. The

Local, Distortional, and Lateral Buckling of I-Beams
Journal of the Structural Division, 1978The finite strip method is used to study the local, distortional, and flexural-torsional modes of buckling of I-beams bent about their major axis. The interaction between these modes is investigated. The buckling loads so determined are compared with those derived using the simpler but approximate theories normally used to design against specific ...

Elastic lateral distortional buckling analysis of cantilever I-beams
Ships and Offshore Structures, 2013A study of elastic lateral distortional buckling of cantilever monosymmetrical I-beams is presented. The method assumes that the flange cross-sections remain straight (undistorted) during buckling, but that the web is free to distort. Three different load patterns are considered: an end moment load, a uniformly distributed lateral pressure and an end ...
