This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract. Lateral torsional buckling is a key factor in the design of steel girders. Stability can be enhanced by crossbracing, reducing the effective length and thus increasing the ultimate capacity. U-frames are an option often used to brace the girders, when designing through type of bridges and where overhead bracing is not practical. This paper investigates the effect of the U-frame spacing on the stability of the parallel girders. Eigenvalue buckling analysis was undertaken with four different spacings of the U-frames. Results were extracted from finite element analysis, interpreted and conclusions drawn. Permanent repository link

“…This problem has been addressed by numerous authors, including Svensson (1985), Williams and Jemah (1987), Bradford (1989Bradford ( , 1998 Johnson and Bradford (1983), Bradford and Johnson (1987), Weston et al (1991), Kemp and Dekker (1991), Bradford and Gao (1992), Dekker et al (1995), Kemp et al (1995), and Vrcelj and Bradford (2009). The contribution of the composite slab to the major axis bending moment can substantially increase the cross-sectional strength of the member in cases where flange local buckling or lateral buckling limit states do not govern.…”

“…Here, the cross-section is assumed not to deform. However, work done by Bradford (1998Bradford ( , 2000, as well as Vrcelj and Bradford (2009) for steel I-section beams suggests that the governing buckling mode would be lateral-distortional buckling for a beam with stiff lateral restraints and a slender web. In this buckling mode, an interaction between LTB and local buckling, the web deforms.…”

Elastic lateral-torsional buckling of glass beams with continuous lateral restraints

Lateral-torsional buckling is a typical buckling mode for slender members loaded in bending, which is characterized by the lateral and torsional displacement of the cross-section along the complete member length. Structural glass members are often connected to the encompassing structure by means of a silicone sealant joint along the member length, which acts as a partially rigid lateral connector, restraining the movement of this side of the member. While this will increase the lateral-torsional buckling resistance of these members, this is currently not considered during the design. In this paper the behaviour of glass beams with a continuously restrained top edge, loaded by a line load or central point load along this edge, will be investigated by executing a numerical parametric study. In this study, the restraint provided by the silicone sealant joint is modelled by lateral springs along the edge of the beam. The influence of the spring stiffness on the critical load and corresponding eigenmode shape will be determined in an eigenvalue analysis, considering both monolithic and laminated glass beams. The results of this study will give some first insights in the influence of lateral restraints on the lateral-torsional buckling behaviour.
