Buckling of stiffeners in plate girder bridge

Webstructural stability of a system of girders connected with cross-frames or diaphragms, during construction stages. This limit state may occur at load levels lower than those required to cause lateral – torsional buckling of individual girders between bracing points; especially, in bridges with relatively long spans and short widths. Webdesign rules for plate girders that utilize the post-buckling strength due to transverse stiffeners of plate girders. With the introduction of plate girders, also came the realization that shear could be carried by means other than beam action. At that time shearing stresses in the webs of plate girders were analyzed
