Our Noahs Prism project demonstrated that Kangaroo2 (a goal-based physics solver for Grasshopper, created by Daniel Piker) can be used for structural design as well as geometrical form-finding. The use of Kangaroo2 within Grasshopper enabled the entire design team to understand the impact of geometric changes and modify the form to distribute loads across the entire net.
Following this project we have teamed up with DTU (Danish Technical University) and post graduate student Cecilie Brandt-Olsen to benchmark the behaviour of Kangaroo2 compared to results from the more ‘conventional’ finite element plug-in for Grasshopper, Karamba, as well as stand-alone packages such as Oasys GSA. The work is progressing with good correlation of results in bending elements, axially loaded elements and structural members with prestressing. An immediate goal is to transfer the technique to more complex structures such as the Dubai Archilace project where traditional finite element based analysis techniques have proven to be difficult to interpret and unreliable in their treatment of second order effects and local failure.
Cecilie, James Solly and Will Pearson will be joining the Calibrated Modelling of Form-Active Hybrid Structures workshop at Smartgeometry 2016 as experts (4-9 April, Chalmers University of Technology, Gothenburg, Sweden).
