Lateral-Torsional Buckling of Parabolic Arches

Journal of the Structural Division, 1972
Equations were derived which govern the lateral-torsional buckling of parabolic arches. Buckling loads were obtained for a uniform applied loading. Both free-standing and crown restrained arches with fixed and hinged end support were considered. A comparison was made, wherever possible, between some of the buckling loads calculated and existing ...

Lateral-torsional buckling of continuous bridge girders

Journal of Constructional Steel Research, 1998
Abstract The resistance of bridge girders with respect to lateral-torsional buckling at support is strongly influenced by the moment gradient. In most design methods this influence is taken into account by the use of a correct critical bending moment in the slenderness parameter λ. This critical moment is influenced by the shape of the moment diagram

Force Combinations Inducing Lateral Torsional Buckling

2021
The phenomenon of lateral torsional buckling can occur when a relatively large transverse load is applied to a thin-walled beam. The article presents the exact equations which give critical combinations of two transverse concentrated forces inducing lateral torsional buckling of uniform rectangular elastic beams. The cases of a simply supported beam, a

Buckling of laterally and torsionally braced beams

Journal of Constructional Steel Research, 1988
Abstract This paper reports on a study of the buckling behaviour of simply supported beams under uniform moment. The beams are braced laterally and torsionally at midspan, and can be doubly-symmetrical or monosymmetrical. A closed-form solution is obtained, the relations between buckling moments and bracing stiffnesses are given and formulae for the ...

Lateral-Torsional Buckling Resistance of Castellated Beams

Journal of Structural Engineering, 2017
AbstractThe existing design expressions for the lateral-torsional buckling behavior of castellated beams conflict. Furthermore, they do not take into account the detrimental effect of the residual stress modification attributable to the fabrication process, which was only recently demonstrated by the authors.

Reassesment of lateral torsional buckling in hot-holled I-beams

, 2020
Lateral torsional buckling (LTB) of I-beams is characterized by simultaneous lateral deflection and twist. In this paper the influence of destabilizing and neutral effects of loadings and the possibility of the occurrence of web distortion, which ...

Lateral-torsional buckling of cellular beams according to the possible updating of EC3

Journal of constructional steel research, 2019
Researchers have not yet reached a consensus on which buckling curve to use for the calculation of the lateral torsional buckling (LTB) resistance of cellular steel beams in the current version of EC3.
