I fail to see what's dumb about using concrete for skyscrapers. Tall buildings have been built this way for over 50 years without issue.

- kevin_thibedeau 9y agoIt's fine for skyscrapers. The Empire State Bldg isn't going anywhere. It's dumb for thin flexible skyscrapers that will accumulate microfractures in a relatively short time span and whose steel structure is insufficient to support the building in the face of significant concrete degradation.
- ggcdn 9y agoMicrofractures =/= global strength loss. Additionally, the concrete itself tends to strengthen over time. I guess I just don't understand what failure mode you are worried about. There are thousands of slender concrete structures that have been in service (thus far) without issue.
