Falsifying the existing theories of geometric stability

I believe that I am heading in a good direction to falsify existing theories for determining geometric stability of complex frames.

If it can be drawn at least one structural frame whose stability cannot be explained by existing theories, it means that they are falsified and a room for new theories is opened.

On my way in trying to falsify existing theories of geometric stability of complex frames, I have drawn three complex frames (orange, cyan and brown) whose geometric stability, I believe, are complicated or even impossible to explain by existing theories.

If someone thinks that he/she can give answers and explanations on whether the three complex frames are geometrically stable or unstable, please contact me with solutions.

Thank you!
