Lateral-Torsional buckling of end-restrained beams

Journal of Constructional Steel Research, 1987
Abstract 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 Nonprismatic I-Beams

Journal of Structural Engineering, 1996
A finite-element formulation for the lateral-torsional buckling analysis of nonprismatic I-beams is developed. The formulation is capable of analyzing continuous I-beams with a linear or quadratic taper within acceptable accuracy. The influence of warping deformations of the section and location of the member loads at different cross-section points are

Neural networks for lateral torsional buckling strength assessment of cellular steel I-beams

Advances in Structural Engineering, 2019

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

Lateral-Torsional Buckling of Tapered I-Beams

Journal of the Structural Division, 1981
The 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

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
