The first hyperbolic paraboloid made of stone is expected to help construction engineers reduce the use of artificial materials in architecture. Using advanced software and robotic fabrication, the New Fundamentals Research Group at the Polytechnic University of Bari and engineers from Roma Tre University designed The HyparGate as an innovative reinforced stone shell which revives Stereotomy, the ancient art of stone cutting.
The shell, located at the headquarters of French company S.N.B.R., is based on the “hypar”, a known doubly-ruled surface commonly used in reinforced concrete shells. It is generated by two families of straight lines called “generatrices”. Its morphological properties allows engineers to easily analyze its structural behavior as a parametric surface and divide stone into modules.
This innovative design draws from Stereotomy to create connections between shape, structure and fabrication, and develop new ways of building self-supported vaulted morphologies through integrated parametric analysis. This computational approach will allow the use of robotic arms and CNC machines in building innovative structures.
