Hello,
I am trying to recreate a fairly realistic model of a roof structure of the Olympiastadium in Munich. The geometry per se was done with Kangaroo form finding in Grasshopper/Rhino environment. It has now been exported in this way: the mesh made essentialy by discretized line elements from node to node in the two main directions (orthogonal mesh). I also have the 'exterior' lines (perimetral) collecting the mesh ends, and mastiles (main supports) and their inclination.
The most complex part is assigning a prestress on the cables (the exterior lines that collect the mesh), that I don't know how to do.
Firstly:
- should I be modelling the cables as Cable elements or Tendon elements? The mastiles are left as frames, obviously.
- which type of analysis should I conduct and where do I assign it?
- how do I assign a prestress only on determinate Cable elements in order to 'stiffen' the roof structure, and reach equilibrium with the mastiles? Is there a way to iterate this automatically? If so, how?
That's it for now,
thank you very much
