Striatus establishes a new language for concrete that is digital, environmentally advanced and circular by design. The footbridge holds together through compression with no reinforcements, applying computational design and 3D printing, for minimal material use and maximum strength.
Philippe Block, co-director of the Block Research Group at ETH Zurich: “The name ‘Striatus’ reflects the bridge’s structural logic and fabrication process. In arched and vaulted structures, material is placed such that forces can travel to the supports in pure compression. Strength is created through geometry, using a fraction of the materials used in conventional concrete beams.”
Shajay Bhooshan, Head of CODE, Zaha Hadid Architects’ Computation and Design research: “Striatus stands on the shoulders of giants: it revives ancestral techniques of the past, taking the structural logic of the 1600s into the future with digital computation, engineering and robotic manufacturing technologies.”
Jan Jenisch, CEO of Holcim: “Striatus was designed by some of the best architectural and creative minds in their fields. It demonstrates the infinite possibilities of 3D Concrete Printing to enable more sustainable, faster and effective building structures, without compromise on aesthetics and functionality. Its digital and circular design uses concrete at its best, with minimal material use and blocks that can be repeatedly reassembled and infinitely recycled.”
George Agriogiannis, CEO of Holcim Australia and New Zealand confirmed that Striatus is made possible by a specific, custom-made ink, from Holcim’s TectorPrint range, developed by its 3D Concrete Printing research team. It sets a blueprint to build for the future using advanced technologies from computational design to 3D Concrete Printing. The next generation of inks can include Holcim’s green building solutions, such as ECOPact green concrete, including recycled construction and demolition waste.
