Lateral–torsional buckling resistance of cellular beams

Journal of Constructional Steel Research, 2015
The evenly spaced circular web openings in I-section cellular beams have an advantageous effect on the material use if these beams are loaded in strong-axis bending. However, not all aspects of the behaviour of such beams have been studied adequately, such as the lateral–torsional buckling failure.

Inelastic Lateral Torsional Buckling of Beams

Journal of the Structural Division, 1981
A numerical procedure is presented for predicting elastic and inelastic beam buckling loads. The procedure uses a finite difference solution to the differential equations defining lateral torsional buckling. The reduction in beam stiffness in the inelastic range is estimated by using an approximate tangent modulus method.

Lateral–torsional buckling resistance of coped beams

Journal of Constructional Steel Research, 2005
The lateral–torsional buckling resistance of beams depends on the support conditions. In floor structures for buildings coped beams are often used. A numerical model was developed to investigate the influence of copes on the lateral buckling resistance.

Lateral-torsional buckling of channel beams

Journal of Constructional Steel Research, 1990
A theoretical and experimental study of the buckling behaviour of channel beams with unbraced longitudinal edge stiffeners, bent in such a way that the stiffeners are in compression, is presented. For a relatively short length of beam loaded in such a manner, the beam will buckle symmetrically.

Lateral-Torsional Buckling of Stepped Beams

Journal of Structural Engineering, 2003
Continuous multispan beams with stepped cross sections at the interior supports are common in construction of steel buildings and bridges. Design equations for lateral-torsional buckling (LTB) resistance in the American Institute of Steel Construction LRFD Specifications in 1998 account for only prismatic and web-tapered beams.

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

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.
