Elastic Buckling of Tapered Monosymmetric I‐Beams

Journal of Structural Engineering, 1988
A finite‐element method of analysis is presented for the elastic flexural‐torsional buckling of non‐prismatic I‐section beam‐columns. The formulation presents a general approach to the problem, in which the coupling of torsion and bending is simplified by adopting the web mid‐height as an arbitrary axis of twist.

Timoshenko beam formulation for in-plane behaviour of tapered monosymmetric I-beams: Analytical solution and exact stiffness matrix

Thin-Walled Structures, 2021
Abstract The presence of curved centroidal axis in tapered monosymmetric I-beams results in coupling between the axial and flexural behaviours. In this paper, an extended Timoshenko beam formulation that incorporates the axial–flexure coupling in the governing differential equations is presented.

Inelastic Buckling of Monosymmetric I-Beams

Journal of the Structural Division, 1973
Considerations of flexural-torsional instability usually govern the design of laterally unsupported I beams. Numerous solutions for the elastic buckling of bisymmetrical I-sections under various loading and support conditions are currently available together with several extensions to cover inelastic behavior.

Distortional buckling of monosymmetric I-beams

Journal of Constructional Steel Research, 1985
Abstract A finite element method which is applicable to studying the distortional buckling of fabricated monosymmetric I-beams is briefly described. The method is used to demonstrate the effects of web slenderness on a monosymmetric I-beam whose smaller flange is in compression.

Lateral distortional buckling of monosymmetric I-beams under distributed vertical load

Thin-Walled Structures, 1996
Abstract An energy method is developed for analyzing the lateral buckling behaviour of beams subjected to distributed vertical load, with full allowance for distortion of the web. The paper presents a simple method which uses nonlinear elastic theory to obtain the external work due to buckling, and which obtains a new formulation of total potential ...

Buckling strength of deformable monosymmetric I-beams

Engineering Structures, 1988
Abstract An energy method of analysis is developed for studying the inelastic distortional buckling of welded monosymmetric I-beams with slender webs. The method uses the Cambridge model of residual stresses. An eigenproblem of order four is developed, and the microcomputer solution of the problem is very rapid.

Lateral post-buckling analysis of monosymmetric I-beams under uniform bending

Journal of Constructional Steel Research, 1994
Abstract The elastic lateral post-buckling response in the vicinity of the critical bifurcational state is examined for the case of a perfect beam, with a monosymmetric I-section, under uniform bending, in which the Wagner effect is taken into account.

Inelastic buckling of tapered monosymmetric I-beams

Engineering Structures, 1989
Abstract A finite element method is presented for analysing the inelastic lateral buckling of tapered, monosymmetric I-beams with general conditions of loading and restraint. The method incorporates the residual stresses produced by welding the flanges to the web.

Inelastic buckling assessment of monosymmetric I-beams having stepped and non-compact flange sections

Journal of Constructional Steel Research, 2015
Abstract This paper presents the finite element analyses made which determine the inelastic buckling capacity of monosymmetric stepped I-beams under uniform bending. The stepped beams analyzed have non-compact flanges and varying degree of symmetry about the x-axis.

Inelastic buckling design of monosymmetric I-beams

Engineering Structures, 2012
Abstract Methods of designing steel monosymmetric I-beams against lateral buckling are not well supported by research. For this paper, the inelastic buckling of monosymmetric steel I-beams under moment gradient is studied and compared with design recommendations.
