Elastic lateral-distortional buckling of I-beams and the Meck Plot

Structural Engineering and Mechanics, 2011
Meck Plot is an adapted version of the well-known Southwell method to the case of lateral-torsional buckling, which indeed reflects the physical inter-dependence of lateral flexure (lateral displacement) and torsion (rotation) in the structure. In the recent reported studies, it has been shown experimentally and theoretically that lateral displacement ...

Lateral torsional and distortional buckling of channel- and hat-sections

Journal of Constructional Steel Research, 1994
Abstract For thin-walled sections, lateral and lateral-torsional buckling are often affected by distortion of the section and this can severely reduce the critical stress. A calculation method for the critical stress which takes account of distortional effects, based on Generalised Beam Theory (GBT), is presented in this paper.

Lateral Distortional Buckling of Monosymmetric Beams under Point Load

Journal of Engineering Mechanics, 1996
Based on a new expression for the work done due to buckling, a computationally efficient method is presented for the lateral distortional buckling of monosymmetric beams. The method requires a knowledge of the stress distribution in the beam. For a simply supported monosymmetric beam subjected to a concentrated vertical load, a simplified stress ...

Influence of Web Distortions on Inelastic Lateral Buckling Length

2021
A critical failure mode is encountered in double symmetric steel I-beams, which is known as lateral distortional buckling (LDB), when the web slenderness ratio of the section is relatively high. LDB is a buckling mode arising through the interaction of the wellknown lateral torsion buckling (LTB) and web buckling, i.e. local buckling (LB), modes.

Distortional and Lateral Buckling of Z-Purlins with Sloping Lips in Flexure

Journal of Structural Engineering, 2018
AbstractA unified model that can be used to study both distortional buckling and global lateral buckling of cold-formed Z-purlins with sloping lips is presented.

Inelastic lateral-distortional buckling of continuously restrained continuous beams

Steel and Composite Structures, 2005
The inelastic buckling behaviour of continuously restrained two and three-span continuous beams subjected to concentrated loads and uniformly distributed loads are studied in this paper. The restraint type considered in this paper is fully restrained against translation and elastic twist applied at the top flange.

Distortional Lateral Torsional Buckling of Doubly Symmetric Wide Flange Beams

2020
Distortional lateral-torsional buckling theories assume that the flanges remain undistorted, while the web is free to distort as a thin plate. Most theories adopt a cubic polynomial distribution along the web height to relate the lateral displacement of the web to the displacements and angles of twist both flanges.
