I don't know maybe there is a link in between this whole thing about structural beams and "OTHER STRUCTURES."

After all... they are all somehow within their own structure?
Or are they?

Well... in structures we have members and nodes.
And we seek for the flow in energy (or load).

We seek that all of that environmental load,
Wind, EarthQuake, Rain, Snow, Dead Load, Live Load (like when the objects get alive).
Get to the ground and dissipate,

And that the remainder (or the structure)
Stays in Equilibrium.
If not...

That's no goood...

So, stops, nodes?
Drives = members?
And could there be significant points of accumulation?
Like bigger nodes?

Yes.

In a structure... like physical as a building, there's stiffness points.
Points where either the mass,
Or the properties of the material used, are capable of attracting more of whatever is flowing through it.

Like bus stations, rather than bus stops.
Places where you've got a loooooot more buses coming through and getting out.
