ELASTIC LATERAL AND RESTRAINED DISTORTIONAL BUCKLING OF DOUBLY SYMMETRIC I-BEAMS

International Journal of Structural Stability and Dynamics, 2010
Based on the energy principle, a theoretical study of the elastic lateral distortional buckling (LDB) and restrained distortional buckling (RDB) of I-beams is presented. First, because the existing potential energy expressions for LDB are not suitable for members under a transverse distributed load, a new general potential energy expression of I-beams ...

Lateral-distortional buckling of tee-section beams

Thin-Walled Structures, 1990
Abstract A fine element method that incorporates plate behaviour is developed for modelling the lateral-distortional buckling of tee-section beams. The method is shown to agree well with independent buckling results for tee-beams. Since relatively few elements are needed to obtain satisfactory convergence, the method is efficient computationally. The

Local, Distortional, and Lateral Buckling of I-Beams

Journal of the Structural Division, 1978
The finite strip method is used to study the local, distortional, and flexural-torsional modes of buckling of I-beams bent about their major axis. The interaction between these modes is investigated. The buckling loads so determined are compared with those derived using the simpler but approximate theories normally used to design against specific ...

Elastic lateral distortional buckling analysis of cantilever I-beams

Ships and Offshore Structures, 2013
A study of elastic lateral distortional buckling of cantilever monosymmetrical I-beams is presented. The method assumes that the flange cross-sections remain straight (undistorted) during buckling, but that the web is free to distort. Three different load patterns are considered: an end moment load, a uniformly distributed lateral pressure and an end ...

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.
