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.

Lateral distortional buckling of monosymmetric I-beams under distributed vertical load

Thin-Walled Structures, 1996
Abstract An energy method is developed for analyzing the lateral buckling behaviour of beams subjected to distributed vertical load, with full allowance for distortion of the web. The paper presents a simple method which uses nonlinear elastic theory to obtain the external work due to buckling, and which obtains a new formulation of total potential ...

Numerical Analysis on Lateral Distortional Buckling of Octagonal Castellated Steel Beams

2018
A numerical model is suggested to predict the behavior of alveolar beams to multiple octagonal openings up to failure taking into account material and geometric nonlinearities in calculation. This research is interested in the effect of web distortions in a lateral distortional buckling mode of the I-beams on simply supported subjected to a load ...

The Effect of Transverse Stresses in Web on the Lateral-Distortional Buckling of Curved I-Beams

International Journal of Structural Stability and Dynamics
Lateral-distortional buckling of framed structures and curved beams made of I-sections may be significantly overestimated or underestimated if the influence of the loading position of transverse forces is neglected. In this regard, this paper introduces a novel beam element that incorporates warping-distortional coupling effects and features nine ...

Elastic Critical Moment of Lateral-Distortional Buckling of Steel-Concrete Composite Beams under Uniform Hogging Moment

International Journal of Structural Stability and Dynamics, 2019
Great attention has been given in the last few years to steel–concrete composite beams due to the gains in strength that can be obtained with the small cost of installing a shear connection between the steel profile and the concrete slab. In continuous and semicontinuous composite beams close to the internal supports, hogging bending moments are ...
