An Increase in Elastic Buckling Strength of Plate Girder by the Influence of Transverse Stiffeners

Steel I girders especially plate girders are subjected to bending, shear and patch loading, so the stability has to be considered in the design. The shear strength in the web panel can be improved by providing transverse stiffeners on both side of the web undergoing a tension field action. Shear buckling strength in the web panel has a significant effect in the shear strength of plate girder. This paper investigating elastic buckling strength of plate girder in which transverse stiffeners are provided in the web. Solution is based on finite element parametric study validated on laboratory tests. After validating the results, provide transverse stiffeners in the web by reducing its thickness and compare these results using specifications of Eurocode, AASHTO,AISC, and British code.
