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 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.

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 ...

Local, Distortional, and Lateral Buckling of I-Beams

Journal of the Structural Division, 1978
The 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 AND RESTRAINED DISTORTIONAL BUCKLING OF DOUBLY SYMMETRIC I-BEAMS

International Journal of Structural Stability and Dynamics, 2010
Based 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, 1990
Abstract 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

Elastic lateral distortional buckling analysis of cantilever I-beams

Ships and Offshore Structures, 2013
A 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 ...
