ELI5: how are the weight on the first floor of a skyscraper able to hold the weight of over a 100 floors?
gpt
The weight goes through the columns (external and internal) which are connected to the piles below the ground. They pretty much only go through compression (and not tension or bending) and materials such as steel and concrete are extremely strong in compression.

The floors themselves only have to hold what is on that floor itself, it's people, furniture etc.
