Robust structures by joint ductility
In view of recent disasters and their immense economical and human consequences, more and more focus is given not only to the safety of structures - to reduce the risk to people of collapse even under exceptional loading - but to minimising the disastrous results and to enable a quick rebuilding and reuse. One crucial way 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 optimised, not necessarily requiring additional fabrication costs. But until now no specific rules for robustness by ductile joints existed. The aim of the present project is to define general requirements for ductile joints as part of a structural system subjected to exceptional unforeseen loading.
