Why they dont immediately remove rubble from a building collapse when one occurs.
In: Engineering
You know that giant arch in St. Louis? Imagine if you took a giant 10 foot chunk out of the top most section center of that arch. What would happen to the rest of that gigantic structure? It’d fall in on itself. Collapsed buildings are far more complex bits and mess that are all resting against each other and there are possibly people under them. So if they take a random thing out, that could cause even the slightest of collapses underneath possibly killing a person pinned in a pocket. Additionally adjusting the weight anywhere can do the same thing so the bits don’t even have to be intertwined, just resting on top. Engineers are trained essentially to treat the pile like a Jenga game, they find the bits that have the least influence on the debri and try to remove them, they also have equipment that scans far into the mess to try to find bodies and people first so they know if an area is safe to disturb slightly.
