Modelling and Statistical Approaches to Lateral-Torsional Buckling
Advanced Materials Research, 2014Some particular and selected problems aimed at ultimate limit state and probability-based studies pertaining to lateral-torsional buckling of steel beams are described. Stochastic analysis of the ultimate limit state of a slender member IPE220 under bending was elaborated.

On the lateral-torsional buckling of non-uniform C-beams
2019This paper experimentally and numerically investigates the lateral stability problem of metallic C-beams with uniformly varying cross-section. The results of a compression test on a physical model are compared with the numerical predictions of the lateral-torsional buckling load given by a variational approach. A good theory vs.

Lateral Torsional Buckling of Wood Beams
2014Structural wood design standards recognize lateral torsional buckling as an important failure mode, which tends to govern the capacity of long span laterally unsupported beams. A survey of the literature indicates that only a few experimental programs have been conducted on the lateral torsional buckling of wooden beams.

Inelastic Lateral-Torsional Buckling of Beam Columns
Journal of the Engineering Mechanics Division, 1965The problem of lateral-torsional buckling in beam columns is studied using an analytical approach to detect the stage at which the inception of this type of instability is imminent. The method adopted uses a forward integration scheme for solving the differential equations defining the problem.

Lateral-Torsional buckling of end-restrained beams
Journal of Constructional Steel Research, 1987Abstract The influence of semi-rigid joint action on the behaviour and strength of laterally unsupported beams has been investigated using a finite element approach. The ultimate strength analysis allows for the effects of initial deflections, residual stresses and the gradual development of yielded zones.

Lateral-Torsional Buckling of Tapered I-Beams
Journal of the Structural Division, 1981The lateral-torsional buckling behavior of non-prismatic beams is not yet fully documented. Using the total change in potential energy during buckling, a fourth-order differential equation in the angle of twist, B, is obtained, in which the location of the transverse load with respect to the centroid is considered.

Force Combinations Inducing Lateral Torsional Buckling
2021The 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 Of Various Steel Trusses
i-manager's Journal on Structural Engineering, 2018Steel parallel chord trusses are most commonly used in the industrial structures and bridges. Different types of parallel chord trusses, include Pratt, Howe, Warren (with and without verticals), K-type, and Diamond type. Various cross-sections that can be provided for truss members are shown in Figure 1.

The buckling curve for lateral-torsional buckling resistance of castellated beams
2008In determining the resistance of castellated beams to lateral-torsional buckling according to Eurocode 3 (EN 1993-1-1) the application of the appropriate buckling curve is crucial. The calculation resistance model to lateral torsional buckling is defined only for bending memebers of constant cross-section and for rolled I-sections (buckling curve a and
