How do floors bend/shake but not break?

577 views

I’ve had a bizarre phobia since I was young. I do not trust the structural integrity of most buildings and am always worrying things will collapse/break. One thing that really triggers my anxiety is when I can feel a floor shaking. If my one year old, 25 pound son can run by and make the floor shake, how can it hold substantially heavier items (like a fridge, washer, etc.)? Please only reassuring comments – I can’t handle this phobia getting any worse 🙂

It’s good when things bend, because they’re avoiding breaking! Wood is a great building material because it is flexible and can take the stresses we put on it as walls and floors for years! Wood also vibrates in ways that make it better for musical instruments than, say, concrete. I don’t really know why that is and I am not smart. But so your floor boards will bend and also carry shockwaves. The floor shaking from someone running on it is just vibrations. If it’s shaking in an earthquake, that’d be something to worry about, but even then, buildings are designed to move a little so they aren’t brittle. Skyscrapers sway like mad in the wind or when the ground moves, and they don’t fall. I hope this is helpful!
