Experiments on Distortional Buckling of I-Beams

Journal of Structural Engineering, 2007
This paper describes a test program on full-scale fabricated simply supported I-beams with central concentrated load and an effective lateral brace at the midspan of the top compression flange that was performed mainly with the aim of experimental verification and investigation of distortion in doubly symmetric I-section beams.

Elastic distortional buckling of overhanging beams

Structural Engineering and Mechanics, 1996
The paper considers the elastic distortional buckling of overhanging beams, which consist of an internal segment with a cantilevered segment continuous over an internal support. The beams were considered loaded by a concentrated load at the cantilever tip, and the beams were either partially restrained or laterally restrained over the internal support.

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.

Understanding of the Buckling Distortions in Silicene

The Journal of Physical Chemistry C, 2012
Silicene, the all Si analogue of graphene is structurally different due to the presence of buckling distortions in the individual six membered rings. The sufficiently strong coupling between the unoccupied molecular orbitals (UMOs) with occupied molecular orbitals (OMOs) leads to pseudo-Jahn–Teller distortion (PJT) and the characteristic buckling in ...

Distortional buckling of elastically restrained cantilevers

Journal of Constructional Steel Research, 1998
Abstract A finite element method of distortional buckling analysis is described briefly, in which the frequently applied 12 degree of freedom beam-type element is extended to a 16 degree of freedom formulation. This extension allows the buckling of beams with a variety of elastic restraints to be modelled accurately. The finite element method is then

Distortional Buckling of Cold-Formed Steel Members

Journal of Structural Engineering, 2006
Cold-formed steel members are widely employed in steel construction because they are lighter and more economical than traditional hot-rolled ones. Nowadays, the easy availability and accessible cost of high-strength low-alloy steels, weathering steels, and zinc-coated steels have led to members with high width/thickness ratios, rendering them even more

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 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

Prediction of buckling distortion of welded structures

Science and Technology of Welding and Joining, 2003
A predictive distortion analysis approach for welded structures is presented. Two-dimensional thermomechanical welding process simulations were performed to determine the residual stress. The critical buckling stress and the buckling mode are computed in a three-dimensional eigenvalue analysis.

Elastic distortional buckling of tapered I-beams

Engineering Structures, 1994
Abstract An approximate finite element method is developed for analysing the distortional buckling of tapered doubly-symmetric I-section beam-columns. The method is applicable for various types to tapering, and various conditions of loading, end support and restraint.
