Long-term lateral-torsional buckling behavior of pin-ended CFST arches under uniform radial loads and temperature field

Mechanics of Advanced Materials and Structures, 2020
In this paper, analytical solutions of the long-term lateral-torsional buckling behavior for the concrete filled steel tubular (CFST) arch with pin ends subjected to uniform radial loads and temperature field are presented.

Experimental and numerical evaluation of inelastic lateral-torsional buckling of I-section cantilevers

Journal of constructional steel research, 2020
A primary failure mode for thin-walled steel members is lateral-torsional buckling (LTB), in which steel cantilever beams experience nonuniform twisting and buckling about their weak axes.

Modelling and Statistical Approaches to Lateral-Torsional Buckling

Advanced Materials Research, 2014
Some 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.

Generalization of the Vlasov theory for lateral torsional buckling analysis of built-up monosymmetric assemblies

, 2020
The present study provides a formal generalization of the elastic lateral torsional buckling solution based on the Vlasov theory, initially intended for monolithic sections, to extend its applicability to any number of cross-sections connected together ...

Buckling of Laterally or Torsionally Restrained Beams

Journal of the Engineering Mechanics Division, 1973
A theoretical study is made of the elastic lateral buckling of simply supported, bisymmetrical I-beams provided with a central brace capable of supplying either lateral or torsional restraint. Loading consisting of either equal end moments, a central load, or a uniform load is considered and the effects of variations in the level of application of both

On the lateral-torsional buckling of non-uniform C-beams

2019
This 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

2014
Structural 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.
