On Structural Behavior of the First Funicular Polyhedral Frame

Published in Architecture and construction magazine 5th issue called “small.

Hedracrete is a unique research project aiming to address three important topics in the field of digital design and fabrication. These subjects include efficient structural form finding in three dimensions, fabrication of complex spatial systems, and the innovative use of conventional materials The form of the structure is a funicular polyhedral frame comprised of both compression-only and tensile-only members with a maximum height of 3.33 m, spanning from three supports located 5.4 m apart from each other. The structure consists of 45 prefabricated joints, 54 compression and 30 tension members sitting on steel supports connected by steel rods. The structural concept has been designed using 3D Graphic Statics which is state-of-the-art geometric structural design method. This approach has been recently developed based on a 150-year-old proposition, and Hedracrete is the first built prototype designed using this method. Thus the structure can be considered a proof of concept for 3D Graphic Statics. What makes the form-finding process unique and intuitive is that by changing the boundary conditions in 3DGS model, a designer can explicitly change the internal forces in the structure from compression-only forces to a system with both compressive and tensile forces.
