Functionally Graded Concrete Building System

Research Project 1-1 (RP 1-1)

IntCDC Research Project 1 – Functionally Graded Concrete Building System
CO-DESIGN OF FUNCTIONALLY GRADED CONCRETE BUILDING SYSTEM

This research project will develop a functionally graded concrete (FGC) building system that is resource efficient in terms of load-bearing capacity, taking into account the specific requirements of multi-storey buildings.

We will develop methods for the design and production of concrete structures that fulfil their functions with minimum material use by synthesising knowledge in materials science, structural engineering and production processes. This work will include the conceptual development of the FGC building system and evaluation of its overall performance for load transfer and building physics. In addition, we will develop methods for the optimisation of components interior, optimised load-adapted joints and the integration of reinforcement in terms of fabrication processes, logistics and construction tolerances. Throughout this project, components will be produced and tested to evaluate their load-bearing behaviour and their building physics performance. The flexibility of the system will be evaluated on the design and production of the demonstrator building.

The development will include design methods, structural systems, building services and building physics, as well as joint systems, in close collaboration with with the Research Projects Cyber-Physical Fabrication of Functionally Graded Concrete (RP 2-1), Multi-Storey Wood Building Systems (RP 3-1), Cyber-Physical Construction Platform (RP 8-1), Robotic Platform for Cyber-Physical Assembly (RP 16-1) and Holistic Social, Environmental and Technical Quality Model (RP 18-1).
