Buckling of Stiffened Webs by Local Edge Loads

摘要: A finite strip method is used for analysing the buckling of longitudinally stiffened web plates subjected to transverse local edge loading. The probLem particular importance box girders, which have relatively weak flanges resisting this type buckling. Critical loads are obtained square webs by single asymmetric longitudinal stiffeners positioned at one fifth depth from loaded edge. sufficient range stiffener geometries considered enable separate influences bending and torsional rigidities be determined two simple design rules proposed. first gives lower limit on rigidity remains straight in buckled configuration. second strength as a function rigidty stiffener.
