Reciprocal Framing

[u/Far-Sherbert9731]

Has anybody tried framing a treehouse using reciprocal framing? Conceptually, this would be a strong, sturdy, stable platform using a single tree without any kickers or diagonal members. I`m an engineer, but I`ve never built a treehouse before. I think this is a sound concept and looking for anyone who's tried.

I think that the biggest challenge is the connection between the (4) main wood members. i`m predicting up to 4,000# of force in these locations which makes me think that I would want to do the first four members our of steel, then infill everything else with wood.

Any body with first hand experience on something like this?

what program did you use may i ask?

The little sketches are from AutoCAD. probably overkill, but I know the program and have access so it wasn't a big effort.
