Designing curves in a Paris pedestrian footbridge

ThinkParametric's Design Playground has published Using Grasshopper and Tekla to Construct a Pedestrian Footbridge in Paris.

It's a complete breakdown of the workflow and strategy used in the design and construction of a footbridge by DVVD Architects at ZAC Claude Bernard. Azhar Khan shares how he and his Elioth team acted as consultants, walking through the process and problems to build the footbridge.

The asymmetrical bridge twists from beginning to end. As the bridge's cross-section is continuously changing, each deck member is unique.

Elioth set up a Grasshopper model to represent the bridge's primary elements. Starting with the architect's Rhino model, they took the geometry to produce a simple model of the bridge's primary steel structure.
