Abstract By adapting concepts for developing modular product families from mechanical engineering to the construction industry, productivity‐enhancing effects resulting from standardized prefabrication and rapid assembly processes can be utilized. As part of the DFG priority program 2187, this research presents an intelligent modularization approach for concrete frame structures that allows for a high degree of architectural freedom. The developed construction kit enables individual building designs featuring both linear and curved structures. Optimization methods were investigated to minimize the internal variety and number of dry‐joint interfaces. The modules and interfaces were designed according to the principles of Design for Manufacturing and Assembly to ensure efficient production and rapid assembly. For this purpose, standardized dry‐joint interfaces were developed, which also allow for damage‐free disassembly using unbonded post‐tensioning. Numerical and experimental studies have demonstrated the ductile structural behavior of the developed interfaces as well as the assembled modular structures. The methods developed were summarized in a reference process for the development of modular construction kits and can also be applied to other construction methods and building types.
