Design of steel and composite structures for robustness

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 loads resulting from a column loss especially the detailed consideration of the behaviour of beam‐to‐column joints is important. A crucial aspect is the investigation of the available rotation capacity of the joints as well as the required rotation capacity of the joints. 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.
