Picture through ETH Zurich
In the garden Marinaressa Park in Venice is a revolutionary technical creation: a 3D-printed footbridge that stands strong without mortar or reinforcement.
Striatus is the name 16 x 12 meters (52.5 x 39.4 feet) of the bridge declared Zaha Hadid Architect’s office “first of its kind”. The name is a nod to its manufacturing process: “Concrete is pressed in layers perpendicular to the main structures to provide a” cross-striped “compression-only cableway.” ArchDaily.
How it works exclusively in the case of compression, the forces applied to it travel towards the platforms, which are fastened together at ground level. And because concrete is applied at certain angles, the layers are kept neatly packed together without additional reinforcement.
The monument was developed by Block the research team ETH in Zurich and Zaha Hadid Architects Group architects. The 53 3D printed concrete blocks used are inkremental3d, Holcim ink, created by experts.
Because the structure does not require mortar, it can be removed like building blocks, then assembled in a different place. Similarly, if it reaches its service life, it would also be easier to dismantle and recycle.
Traditional confirmed Concrete and steel used in buildings produce huge amounts of CO2 emissions during production processes worldwide, not to mention traffic and construction itself. The creation and existence of this bridge and the newly opened bridge Amsterdam, shows that our infrastructure may be towards a less harmful future.
Striatus is on display at the Giardini della Marinaressa during the Venice Architecture Biennale, which runs until November 2021.
