Striatus − a bridge of 3D-printed concrete

For the 17^th Biennale of Architecture in Venice, the Block Research Group from ETH Zurich and ZHA CODE − the research department at Zaha Hadid Architects − have created a vaulted bridge of 3D-printed concrete elements. Incremental3D (in3D) of Innsbruck printed the elements using a type of concrete newly developed by the manufacturer Holcim.

The video by naaro shows the bridge, whose construction was inspired by vaulted shapes from the Middle Ages. Its components, which were assembled without mortar, are subject only to compressive loading. Along with the distribution of forces, the video depicts the manufacture at the workshop in Innsbruck, the shipping of the individual components to Venice and the assembly of the bridge on site.

We feature this project in Detail 10.2021.
