The primary problem with the tower is its supports. To see why, let’s separate the vertical part (core) of the tower from the square base, and examine the base more closely. The applied load transfers to the base through the core as shown below.
So, if I draw a diagram of the base only, it is going to look something like this:
Here, the blue lines represent the existing members, the red arrows represent the forces that are applied to the base from the core, and the green triangles represent the supports (points of contact between the base and the testing platform ). The problem here is that there are no vertical (or close-to-vertical) members carrying the red forces to the green supports. The base consists entirely of horizontal members. Given the small size (3/32 x 3/32) of these members, they would have a very difficult time withstanding the loads and effectively transferring them to the support points.
Here is a suggestion for remedying the problem.
1. Have inclined members directly transferring the load from the core to the supports, as shown below.
2. Brace the inclined members to prevent instability (buckling), as shown below.
3. Eliminate most of the members in the lower part of the tower, except for the horizontal bracings at the base, as shown below.
The revised design should result in a stronger, and probably lighter tower.
