Who sets municipal limitations on the height of concrete buildings?
It's strange that you should ask. Vincent DeSimone and James Chaplin, in a recent engineering data sheet from the New York Concrete Construction Institute, say that it would be interesting to study who does set these limitations. Maybe they're not always formally set. A decade ago, they say, it was commonly said that all residential buildings in New York were flat plate concrete and all office buildings were steel. At that time there was a self-imposed limitation of about 30 stories for concrete, though now it is 40 or 50 stories. Actually there are no structural, architectural or construction limitations on the heights concrete can attain, according to these professional engineers. Chicago now has six buildings of 50 to 77 stories. Sydney, Australia has one of 70 stories; Buenos Aires one of 63 stories; Houston one of 52 stories; Atlanta, New York and New Orleans one each of 50 stories, and Miami one of 40 stories. Good design, better construction techniques, and the growing availability of 8000 psi concrete contribute to the use of concrete in higher buildings.
