[en] In view of recent disasters and their immense economical and human consequences more and more
focus is given not only on the safety of structures - to reduce the risk for the life of people by collapse
even under exceptional loading – but on minimizing the disastrous results and to enable a quick
rebuilding and reuse. One crucial mean to achieve this aim is the design of redundant robust structures.
Robustness prevents the collapse of the total structure when only parts of the structure are damaged or
destroyed. To avoid progressive failure, redundant structures with inherent sufficient ductile behaviour
allowing deformations when a local failure occurs, have to be built. Redundancy can be achieved by
allowing force redistribution within a structural system. Therefore the single sections and joints have to
be especially designed and optimized, not necessarily requiring additional fabrication costs. But until
now no specific rules for robustness by ductile joints exist. The aim of the present project is to define
general requirements for ductile joints as part of a structural system subjected to exceptional unforeseen
