ABOUT THE PROJECT [official page]
How can we design Circular Concrete Structures for Additive Formwork?

Taking advantage of Additive Formworking techniques and computational 3D Graphic Statics form-finding method, 3D Polyhedral Structure – Additive Formwork challenges the use of Ultra High Performance Fiber Reinforced Concrete (UHPFRC) by proposing a structurally efficient and flexible construction system composed of discretized complex elements and moment-based double curvature roof modules.

Through an integrated design to fabrication workflow definition, a series of full-scale structural elements (nodes and struts) are produced and verified in the CREATE Lab at SDU.

The project is the development of a previous investigation 3D Printing for Circular Construction (3DPCC) on the use of additive manufacturing to realize accurate concrete circular construction.
