Skyscrapers construction in USA in 1930s.

 







In the previous article we talked about the smallest women in the world. Now we will show photos of the constraction of the tallest building in the USA in the 1930s.

Several technological advances occurred in the late nineteenth century that combined to make skyscraper design and construction possible. Among them were the ability to mass produce steel, the invention of safe and efficient elevators, and the development of improved techniques for measuring and analyzing structural loads and stresses.

During the 1920s and 1930s, skyscraper development was further spurred by invention of electric arc welding and fluorescent light bulbs (their bright light allowed people to work farther from windows and generated less heat than incandescent bulbs).

The 792-ft (242-m) tall Woolworth Building, erected in New York City in 1913, first combined all of the components of a true skyscraper. Its steel skeleton rose from a foundation supported on concrete pillars that extended down to bedrock (a layer of solid rock strong enough to support the building), its frame was braced to resist expected wind forces, and its high-speed elevators provided both local and express service to its 60 floors.

Perhaps it is just because most syescrapkrs out there are not green, since during their design some few decades ago, the designers had no intention of making them even remotely green. Green has just never been a consideration until quite recently. Bu
