Cyber-Physical Fabrication of FGC Components

Research Project 2-1 (RP 2-1)

IntCDC Research Project 2 – Cyber-Physical Fabrication of Functionally Graded Concrete
CYBER-PHYSICAL FABRICATION OF FUNCTIONALLY GRADED CONCRETE COMPONENTS FOR MULTI-STOREY BUILDINGS

The project concerns the development of a fabrication platform for functionally graded concrete components, developed in Research Project RP 1-1, which are optimised for resource efficiency in terms of load-bearing capacity, taking into account the specific requirements of multi-storey buildings.

Based on the geometric, mechanical and building physics requirements from RP 1-1, the work will focus on conceptualising the overall design-to-production process chain, defining production processes for internal gradients, joints, external formwork, and casting and assembly systems. The process integrates digital implementations of design and optimisation methods with physical processes – such as fine-tuned mixing of high-performance concrete and its precise extrusion – and digital methods for process planning and control.

The overall requirement is to minimise the weight of the components, to extend the capabilities of fabrication to on-site application and to minimise the environmental impact of their manufacture in order to meet today's social and ecological challenges and to ensure the creation of a liveable environment for future generations.

The project will be carried out in close collaboration with the Research Projects Co-Design of Functionally Graded Concrete Building System (RP 1-1), Cyber-Physical Construction Platform (RP 8-1), robotic platform for cyber-physical assembly (RP 16-1) and Holistic Quality Model (RP 18-1).
