Özet

Lateral torsional buckling and shear buckling are two of the most significant structural responses that should be considered during the design process of plate girders.Particularly the importance of lateral torsional buckling was once again witnessedduring the reconstruction process of a bridge in Edmonton, Alberta, Canada when theplate girders failed due to insufficient bracing. This current study aims to acquire abetter understanding of the effect of geometric parameters such as the web slenderness, flange slenderness and span-to-depth ratio on the critical buckling moment andultimate shear strength of plate girders. To achieve this goal the critical buckling moment and ultimate shear strength of a plate girder were parametrically studied for alarge number of geometries using a load case from an experimental study. The resultsof this parametric study clarified the effects of web slenderness, flange slendernessand span-to-depth ratio on the structural performance of a plate girder. The visualization of the results was used to identify the ranges of these geometric parameterswhere the structural performance is most sensitive to changing them.
