When we’re taught about vibrations, every mathematical modelisation deals with a system of a fixed spring whose end has a certain mass, but how does this relate to real-world systems like a bridge or a building? The natural frequency of the spring-mass system is the number of back-and-forth movements being done per second, but what’s the equivalent of that for let’s say a building or a bridge or any real-life application?

The analogy is pretty direct, the bridge itself moves up and down because the atoms around bound together like with springs (by electromagnetism)
Just the parameters are very different, the springs are very strong so little movement means high forces already.
