The 632 - meter Shanghai center building

Many innovation center in Shanghai will become the standard of the next generation of skyscrapers. Increasingly advanced engineering technology allows architects to the building has more than 1000 meters high.
Technically, as defined by the world top urban construction institute, the so-called super-tall skyscrapers refers to a height of more than 300 meters, or 984 feet of a building, including the Empire State Building is 381 meters high. The Empire State Building in New York in the term "super-tall skyscrapers" formally before the advent of half century, always keeps the crown of the world's tallest building. Started in 1966, the height of the towers of the world trade center in New York had reached 417 m and 415 m respectively. But until 15 years ago, the architects and engineers began to tall building as a separate category. This classification means new challenges and opportunities. "Height over the twin towers in the design of buildings, must change the design idea and technology of the most basic." Baker said.
Today's high-rise buildings in both the design and selection of material and once upon a time there was a big difference. , once the choice of super-tall steel, but engineers have begun to use concrete to replace steel.
