Lateral-torsional buckling of high strength steel beams: Experimental resistance

Thin-walled structures, 2021
EN 1993-1-1 gives stability design rules for columns, beams and beam–columns up to S460, whereas EN 1993-1-12 gives additional guidance for S500 up to S700.

Behaviour of corrugated web girders subjected to lateral-torsional buckling: Experimental tests and numerical modelling

, 2021
Corrugated plates are gaining increasing attention from researchers based on their recent extensive use in structural engineering, thanks to their potential to provide lighter and more economic structures.

Lateral-torsional buckling (LTB) method for the design of glass fins with continuous lateral restraints at the tensioned edge

, 2021
The lateral torsional buckling (LTB) analysis of glass members is a well-known issue, and can be critical for the design of glass fins that are used to brace slab panels or walls and facades .

Lateral Torsional Buckling of Split Aluminium Mullion

Key Engineering Materials, 2016
Curtain wall industry is the major user of aluminium as a structural material in buildings, with two basic curtain wall systems: stick and unitised. The latter is preassembled in shops, with the main feature that frame profiles are split in two interlocking halves. Such cross sections are complex, open and prone to lateral torsional buckling.

Lateral-torsional buckling behaviour of concrete-filled high-strength steel tubular flange beams under mid-span load

, 2021
Lateral-torsional buckling (LTB) behaviour of concrete-filled high-strength steel tubular flange beams (HS-CFTFBs) is experimentally and numerically investigated. Six specimens are tested in simple support with a lateral unrestrained concentrated load in

Lateral–torsional buckling resistance of cellular beams

Journal of Constructional Steel Research, 2015
The evenly spaced circular web openings in I-section cellular beams have an advantageous effect on the material use if these beams are loaded in strong-axis bending. However, not all aspects of the behaviour of such beams have been studied adequately, such as the lateral–torsional buckling failure.

Development of consistent buckling curves for torsional and lateral‐torsional buckling

Steel Construction, 2008
AbstractThe stability design of beams and columns for lateral‐torsional and torsional buckling is generally treated in the new Eurocode 3‐1‐1 [1] by using the same buckling curves used for flexural buckling. These buckling curves are expressed mathematically in terms of a function χ($ \bar \lambda $), which was derived in [2] and [3] by combining a ...

Inelastic Lateral Torsional Buckling of Beams

Journal of the Structural Division, 1981
A numerical procedure is presented for predicting elastic and inelastic beam buckling loads. The procedure uses a finite difference solution to the differential equations defining lateral torsional buckling. The reduction in beam stiffness in the inelastic range is estimated by using an approximate tangent modulus method.

Lateral–torsional buckling resistance of coped beams

Journal of Constructional Steel Research, 2005
The lateral–torsional buckling resistance of beams depends on the support conditions. In floor structures for buildings coped beams are often used. A numerical model was developed to investigate the influence of copes on the lateral buckling resistance.
