Distortional Buckling Solutions for Continuous Composite Beams

Inelastic restrained distortional buckling of continuous composite T-beams

“…Bradford and Trahair [24] studied the inelastic lateral-torsional buckling of restrained continuous beam-columns using a finite element method developed by Bradford [25] and verified it with an experimental study conducted by Cuk et al [26]. Bradford and Johnson [3] and Johnson and Bradford [27] considered composite cross-sections, while Bradford and Gao [28] investigated the elastic lateral-distortional buckling of continuous composite beams. Lee [29] studied the inelastic RDB of two and three-span beams under transverse load, fully restrained against translation and elastically against twist at the top flange.…”

Beams

“…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.…”

Rotational Stiffening Performance of Roof Folded Plates in Torsion Tests and the Stiffening Effect of Roof Folded Plates on the Lateral Buckling of H Beams in Steel Structures

“…One member that is continuously affixed to a beam in an actual structure is a floor slab. The lateral buckling of beams, with floor slabs serving as composite members of steel and concrete, has been examined [31][32][33][34][35]. Here, the floor slab is replaced by a continuous spring, facilitating the numerical analysis of the effects of horizontal deformation of the compression flange [36] and the bending and torsional deformation of the beam [37] on the lateral buckling load.…”
