N2 - In general, two types of launching bearings are used for launching: Sliding rockers and systems with hydraulic bearings. During incremental launching, the centre of the webs of the superstructure is not perfectly in line with the centre of the launching bearings due to unavoidable tolerances. These eccentricities are not considered in the current design against plate buckling according to EN 1993-1-5 [2]. Furthermore, there is a significant difference between the different types of launching bearings due to the boundary conditions. At the Technical University Munich, large-scale buckling tests on longitudinally stiffened plates under biaxial stresses with different types of launching bearings and eccentric load introduction were carried out. The results from the validated numerical model and parameter study of the influence due to different types of launching bearings on the buckling behavior are shown. The results are compared with the buckling verification according to the reduced stress method proposed in EN 1993-1-5:2019 [2].
