ABSTRACT
ABSTRACT The paper briefly reports on investigations concerning the robustness of steel and composite structures. When applying the alternate load path method for redistributing the loadings resulting from a column loss especially the detailed consideration of the behavior of beam-to-column joints is important. A crucial aspect is the comparison of the available rotation capacity of the joints with the required rotation capacity of the joints in the system. Finally a method is presented that can be used in order to verify the rotation capacity for permanent load situation as well as for accidental load situations.
