Skyscrapers -What makes one a ?

This is my very first thread here, so hi everyone. Please excuse my ignorance as I'm not an Architectual bod. Can anyone tell me what designates a building a skyscraper?

Does it have to be so many floors, or is it the way it is built (ie with gerders)?

I recall a programme some years ago, about the first sky scraper being in America.


Please help educate my ignorant mind.

Thanks
Purdy

The general definition I use is any building higher than 100 metres, from ground level to the top of the roof. I know some people use 150 metres, as well... I honestly don't think there's a formal definition of what a "skyscraper" is. It also changes based on time... in 1910, a 75 metre high rise would probably be called a skyscraper, for example.

Thats 492.125984252 feet. IF i am correct that is the length of the straight and a half on the normal atheletics track, or a tad over an average footie pitch.

The vast majority of people consider a skyscraper as being a minimum of 150m. See the poll results in this thread -

http://www.skyscrapercity.com/showthread.php?t=495066

The roof/spire height is debatable, but personally I think spire heights should be counted. They're part of a building's structure, after all. When measuring the world's tallest skyscraper, the Council on Tall Buildings and Urban Habitat has several definitions as I understand it (for example - tallest skyscraper to roof, tallest to spire, tallest to occupied floor, etc...).

That's why I said that it's the definition I use. Again, there is no formal definition of what a skyscraper is, and it's something that changes over time.

I don't like including spires, myself, since their usually just a radio tower stuck on the roof of the building, and not really a true extension of the structure. Again, this is up for debate, though.

Stick a 75m building in a traditional-looking low-rise village today and you can bet they'd call it a skyscraper.

A few lines from the song Kansas City in the 1943 musical Oklahoma! (where the gag is that from the perspective of the OK farming folk, Kansas City is a mighty and sophisticated metropolis - presumably the Broadway audience might have seen it differently):

Ev'rythin's up to date in Kansas City
They've gone about as fur as they c'n go!
They went and built a skyscraper seven stories high,
About as high as a buildin' orta grow.

I think it depends on the city.
Here in Christchurch, the tallest building is 76 m, and I would consider it a skyscraper. It think it also depends on the building, and how much it stands out.
