Beulverhalten längsausgesteifter Platten unter Interaktion von Biegung und Querkraft

Buckling of slender plates due to bending-shear interaction - Experimental and numerical Investigations.

In this paper the bending-shear interaction of slender plates is studied. Six large tests were performed on longitudinally and transversally stiffened girders in the range of high bending moment and shear force. In longitudinal direction the webs were stiffened with a trapezoidal stiffener positioned at the mid web depth for two girders and in the compression zone for the other four girders. Furthermore, a numerical model built in the general-purpose code ABAQUS is presented and verified against test results. In the final part of this paper the maximum load and the design resistance according to EN 1993-1-5 are compared and discussed. The design resistance was calculated with both options, according to the effective width method and the reduced stress method.
