Reinforcement again: it goes forth

Again, I’d like to share here some recent progress made about placing Reinforcement on irregular shapes, like a slanted double curved wall here. I managed to put some Structural framing to act like rebars, as a Design intended model only for now. No shop drawings yet.

Rebars WIP 3

The good point with SF families is that one can apply offset in Y and Z direction, which is just fine in this case to act like a cover setting. Select all, apply setting, done.

Another good one is that you can schedule those “acting-like” rebars, and eventually make some QTO and cost estimating. I need that feature, that’s why I want to stay in the project environment.

Let´s see in detail some nodes I use for this and how I get it work. You will discover with Dynamo that succes comes if you’re good at playing stacking games.

My point is that you add things and you don’t stop until it falls down. Then you start again….and if you have some success, it looks weird. See above picture.

First part of the dyn file is about getting points from a UV grid that are NOT on the borders:

Rebars Select face

Thanks to the packages, you have the ability to reuse some cool nodes made by others, here by Andreas Dieckmann. Here you select the face, number of rebars in both directions, and you get UVs.

Then you have to sort those points so that the borders of the surface are not hosting points anymore. Was a stacking game. And I can’t really remember how I get there, but it works.

Rebars create grid no borders

In this last part, once you have the points, you use them to get curve and apply Structural framing on. Be careful, getting the Up direction is not as easy as it looks. Give a try.

Rebars create SF

I must admit it’s a bit slow to refresh, but I guess that my way of dealing with lists and sorting elements should be improved to react faster. Maybe some enhancement from the Dynamo development team for performance improvement could help too.

Dyn file can be found here.

Next steps:

  1. allow 2 faces selection
  2. manage spacing in each direction, not only by number of rebars but with a distance
  3. find a way to mock-up stirrups at the edges of the shape
  4. deal with triangular surfaces

See you soon, with a video to show how it works.
