N2 - Six large-scale buckling tests were carried out at the Technical University of Munich, at longitudinally stiffened plates under biaxial stresses in 2018. During the tests, parameters such as the stress ratio σz /σx, the stiffness of the stiffeners and their distance were examined. The stiffeners were designed as closed trapezoidal stiffeners. The influence of the torsional stiffness of longitudinal stiffeners with closed cross sections on the buckling behavior of plates is currently part of scientific research and is controversially discussed with respect to a new standard definition in Europe. According to the current state of knowledge, the torsional stiffness has to be neglected for the buckling verification according to EN 1993-1-5:2006 [1]. This is based on the background report TWG89 [2]. Based on the test results, a numerical model was validated and influences such as the stress ratio σz /σx, torsional stiffness and imperfections were investigated.
