Looking great Celt83! Congrats on the fantastic work and welcome to the club of structural engineers turned into software developers :)

Sure, I'm very happy to share these details with you, but would prefer to avoid posting that information here. Feel free to reach out via email (tribby3d at gmail dot com) and I'll tell you more.
I suppose the assumption here is that every floor is identical?
Appreciate this input, thank...
Yes, the tributary area method certainly has its flaws, like, you say, scenarios with backspans and cantilevers.
If you don't use the tributary area method for calculating design loads in early stage concept design, how do you else do it? Do you build an early stage FE model, even for...
Thank you! Good to know. It is a fine balance between making the tool sufficiently accurate and simple enough to use. I'm constantly trying to find this balance with Tribby3d.
As mentioned in the answer to KootK - I don't know. The focus right now is to make Tribby3d a useful and valuable tool...
Interesting. I'll have a look at this. I heard that RAM Concept also has a similar graph-based approach for solving one-way systems without FE. Do you know anything about that?

Good to know! I suppose that assumes that the entire floor is continuous then? Otherwise I suppose you would have to do a similar redistribution wherever the floor continuity is broken.
Not sure if I understand this fully. Isn't this what Tribby3d does?
Thanks for the feedback dik. Appreciate...
Yes, really good points. The backspan/cantilever effect is also tricky, and also more or less impossible to account for with the current geometric approach. I didn't realize alternating short and long spans could bring similar effects. I'll include this in the documentation. Thank you!
This is...
Makes sense. Adjustment factors would be one way of dealing with this. Do you think that this is something that should be built into Tribby3d? Or is it better to deliver the "raw" areas, and let the users adjust the results based on their own judgement?

You are right. The difference between continuous vs discontinuous could be up to 25% (0.625/0.5 = 1.25). However, I'm afraid that there is nothing that can be done to account for this with the current geometric approach that Tribby3d uses. Is this a deal-breaker in your opinion? Tribby3d is...
Thanks a lot for the feedback Tomfh. Could you please help me understand how the continuity of the slab affects the tributary area? Does this have to do with moments induced if the slab isn't "released" at the supports? I am aware that slab directionality (like one-way systems) and column...
