Question

Here’s an [example](https://youtu.be/NnUeipeDCZ8) of what I mean.

Answer 1

This is not a column but a pipe. You must realize that the wall of the pipe not only supports the weight above it, but it also pulls the wall down it, for example, the wind blows from that side (or else the wind would topple the pipe over).

From that you can see that the example is an accident: it might have been the wind.
