collaborative research center 1683 – interaction methods for the modular reuse of existing load-bearing structures
Interaction methods for the modular reuse of existing load-bearing structures
The aim of the CRC is to investigate the reuse of concrete elements on structural level and to develop fundamental scientific methods for this purpose. Sustainability guides the methodology. The idea is not to demolish existing structures in an uncontrolled manner, but to deconstruct them rationally into modules. The modules are characterized regarding their properties, refurbished and joined into new structures in a modular fashion. Detachable connections make these new load-bearing structures circularly reusable. Moreover, they are adaptable to future changes in use and allow the exchange of modules and the integration of new elements, thus creating a circular modular construction. Existing foundations become foundation modules and attractors when defining new structures. The CRC is structured into three project groups (PG) A, B and C as well as a project for information infrastructure.
Project group A addresses new load-bearing structures made from existing elements. PG B is dedicated to the adaptive characterization of the actual condition of existing modules on material, structural and sub-element level. PG C deals with the overall process including the modular construction kit and automation concepts.
The collaborative research center is funded by the German Research Foundation DFG since 2025. Within the first funding period (until 2028), around 70 researchers from the Ruhr University Bochum (RUB), the Karlsruhe Institute of Technology (KIT), Stuttgart University and Bundesanstalt für Materialforschung und -prüfung, Berlin, collaborate jointly.
