Swiss public research university ETH Z\u00fcrich has teamed up with Zaha Hadid Architects to create a new type of bridge that uses less material and enables new types of forms.<\/p>\n\n\n\n

By 3D printing concrete at specific angles, the collaborative team was able to produce blocks with layers “orthogonal to the flow of compressive forces,” allowing them to design differently-shaped blocks for different portions of the bridge.<\/p>\n\n\n\n

On-site these blocks are fitted together in the manner of traditional stone arches\u2014i.e. the structure is self-supporting\u2014but the arrangement allows for wildly organic shapes that no traditional stonemason could ever hope to work out on paper<\/p>\n\n\n\n

The blocks stick together through gravity, meaning no mortar is required. No steel reinforcements are necessary, either. And if needed, the entire bridge can simply be disassembled and reassembled elsewhere.<\/p>\n\n\n\n

However, as with 3D printing certain forms in plastic, temporary support is needed. In this case, a rather comprehensive OSB scaffolding has been erected, with the parts having undoubtedly been cut with a CNC mill. This should offset the resource savings somewhat, but we assume that on-balance, they’re still in the black.<\/p>\n\n\n\n

Analysis<\/h2>\n\n\n\n

This article was interesting to me because of its creative use of interlocking components. 3D printing can be tricky when it comes to elevated or lofted parts so I thought it was intelligent to pre-fabricate the concrete parts and put them together on site. This requires a certain level of planning and problem solving.<\/p>\n\n\n\n

Although I do not know what my final project will be yet, I want to keep an open mind about the structure’s form. Perhaps there is room for negative space. <\/p>\n\n\n\n

Take-Aways<\/h2>\n\n\n\n

Concrete may seem hard to work with when it comes to overhangs and arches, but pre-fabrication and creative problem solving can help create ways around it. <\/p>\n\n\n\n

Concrete does not have to be bulky, it can be elegant and innovative.<\/p>\n","protected":false},"excerpt":{"rendered":"
