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.

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 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 ...

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 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.

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.

Experimental and numerical investigation on LTB strengths of monosymmetric compact I-beams with thickness-stepped-flanges

International Journal of Steel Structures, 2015
This paper investigates the inelastic lateral torsional buckling, LTB, of doubly stepped singly symmetric compact I-beams under two concentrated loads. The results are obtained by conducting actual destructive tests on the beams using a testing machine and running simulation tests using the finite element program, ABAQUS.

An Energy Approach to Elastic Stability Analysis of Multiply Braced Monosymmetric l-Beams

Mechanics of Structures and Machines, 1989
ABSTRACT This paper investigates the elastic stability of multiply braced cantilevered and simply supported monosymmetric I-beams. On the basis of the Timoshenko energy approach, a generalized Rayleigh quotient is derived. The buckling capacity can then be obtained by solving an optimization problem in which the Rayleigh quotient (the objective ...

Elastic lateral-torsional buckling strength and torsional bracing stiffness requirement for monosymmetric I-beams

Thin-Walled Structures, 2016
Abstract Elastic lateral-torsional buckling (LTB) is a common failure mode of large span beams. In this phenomenon the beam becomes unstable along the unbraced length. This instability of beams can be identified by out-of-plane deflection and twisting. Using discrete torsional braces is one of the ways to prevent LTB.
