Thanks for that pix.

You don’t have to be a structural engineer (and I’m not) to see that any sort of torque (twist) failure and that thing liquifies.

I am willing to believe that the Y-axis is adequately braced against compressive (downward) forces, by the zig-zag [concrete] girders. But that is exactly and only at a perfect 90 degrees from horizontal. On a perfect vertical chord.

Any twisting starts an immediate progressive crumbling failure. That design is utter horses**t, modeled on a 2-D computer screen by someone with zero real world experience.

Yup
