【 摘 要 】

This paper intends to provide an overview on large-scale buckling tests, which were carried out at the Technical University of Munich in January 2018. In the experiments, the load introduction was simulated as it usually occurs during incremental launching of a steel bridge when a biaxial stress state from direct stresses from the bending moment due to cantilever action and local transverse compression stresses due to load introduction at the bearings occurs. The topics and background of the research project will be presented, explaining the test program as well as the structure of the whole test setup and first numerical calculations. Initial results from the experiments are presented and compared with the numerically validated model, which is carried out at the University of Stuttgart. For this purpose, two of the specimens are compared and differences of their buckling behavior are analyzed.
