Parametric model structural bridge design - easy explained

parametric model structural bridge design easy explained
Check out this beautiful bridge design by Ney & Partners. This video explains how to prepare a Rhino Grasshopper model for structural analyses using Karambda3D plugin.
This video is part one of a series of three videos. The second video covers the use of Karamba3D structural shell analyses. The third video explains how to generate a large number of design options and use design explorer by CORE studio-Thornton Tomasetti, to find the best possible outcome.
For calculation speed purposes the perforations have been left out.

So what is the parabola expression of 7:34 s?

The expression is "-x" which makes all positive inputs negative. You can also use the native Grasshopper negative node, or just input a negative number.
