Critical rigidity of stiffener for increasing shear stability of rectangular plate
Keywords:clamped rectangular plate, shear, buckling, finite element method, dimensions of stiffener, experiment
In plate girder with slender web the big transverse forces lead to web buckling produced with shear. One of the ways to increase stability of web near supports is to install stiffeners. In work the task of finding of critical stresses of clamped rectangular plate with installed inclined stiffener is considering. Investigations were performed with the finite element method and were checked with the experiment. Recommendations were given on choice of optimal size of stiffener.
