Structural Column Tributary Area

Looking for strategies for achieving this. Any thoughts?

I am thinking the following
-Use existing Floor corners for a new surface face
-Use existing Structural column xyz for uvs in Voronoi
-Allow the Voronoi to do all the sub dividing of the surface

-some how want to end with something i can select and get the area to do my structural calcs with

This is a problem best solved in a structural analysis software. Dynamo’s primary focus is geometry and trying to solve this problem from a purely geometric aspect, would be a very extensive task. There would be a lot of edge cases that you’d have to address and your Revit model would have to be modeled to perfection.

Not saying that the task is impossible but I highly doubt that Dynamo’s the best way to approach this.

Here’s brief example to get you started. I’m using the analytical model because it has a higher tolerance to common modeling mistakes. The below example works only because my model is very simple and completely symmetrical:

A more complicated solution would have to involve walls as well, it would need to figure out exactly what portion of each slab surface area goes towards each support, etc.

I have not looked at this myself- but could be relevant

Hi, have you looked into the Gravity analysis function in Revit? https://www.youtube.com/watch?v=786iJwu5_Ws
Haven’t tried it to extent myself but looks promising for obtaining what you want. Maybe there is some API calls for the results as well, @Dimitar_Venkov?

@James_Brokaw The problem ends up being really very difficult especially when you have openings and irregularly shaped slabs. My suggestion is look into this blog http://react.autodesk.com/blog/

I like to use area plans for load takedown in early stages.

  • I use Dynamo to create area boundaries between each grid line
  • Write the grid intersection (e.g D/5) to a parameter of the area.
  • Then add loads and accumulate the load * area down to the foundations.

Wow,overwhelming support here. Thank you all so much!

On Monday I am going to pick this back up. Had a deadline to hit yesterday.

It always amazes me the bad asses on forums that take their time to not just offer a few words but examples. Truly! Thank you.
