WebLateral torsional buckling A typical bridge girder with a portion of the span, over which the compression flange is laterally unrestrained, is shown in Fig Such a girder is susceptible to lateral torsional buckling. Fig shows a laterally buckled view of a portion of the span. WebWays to Brace a Beam. Per AISC 341, there are two methods to brace the beam: (1) lateral bracing (Figure 3) and (2) torsional bracing (Figure 4). Under lateral bracing, …

WebAug 7, 1998 · The location of the lateral bracing on the cross section has a significant effect on torsional buckling. Equations are developed for the stiffness and strength … Webwhere lateral/torsional restraints are provided at the tension flange. Samanta and Kumar (2008) investigated the distortional buckling beams braced at the top flange, bottom flange or both flanges through shell FEA under Abaqus. In the current study, three lateral torsional buckling solutions are provided for two case studies. The first
Webbrace beams to resist lateral-torsional buckling. Lateral-torsional buckling can be restrained by a torsional brace or a lateral brace. That is, the brace can either prevent twist or lateral displacement of the compression flange relative to the tension flange. Most details provide some combination of these restraint mechanisms.
