Lateral Torsional Buckling Resistance of Gerber Beams Under Gravity and Uplift Loads
A recent study developed a family of finite elements for determining the elastic buckling strength of beams with wide flange sections. The formulation accounts for web distortion by treating it as a Kirchhoff thin-plate while treating each of the flanges as a Vlasov beam. The solution is equipped with the features needed to model the Gerber beam systems: (1) evoking or eliminating web distortional effects, (2) inserting discrete lateral restraints at any or both flanges at user-specified locations, (3) providing a distortion diagram that characterizes the distribution of web distortion along the span as the beam buckles laterally, and (4) incorporating transverse stiffeners into the model to suppress distortion at user-specified locations. By exploiting these features, a systematic design methodology is developed to optimize the transverse stiffener configuration, thus maximizing the critical moment resistance of Gerber beam systems. A systematic parametric study is then conducted for the problem and recommendations are made for optimizing their lateral torsional buckling resistance under gravity and uplift loading.
