Skyscraper, also known as super high-rise building, is a very high multi-storey building. Originally a building with 10 to 20 floors, now it usually refers to a high-rise building with more than 40 to 50 floors. With the development of high-rise buildings in different places, people's understanding of the definition height of skyscrapers is slightly different. In Chinese mainland, the building code stipulates that the height above 100 meters belongs to super high-rise buildings; Japan and France, which are over 60 meters, belong to super high-rise buildings; In the United States, buildings over 152 meters (500 feet) are generally considered as skyscrapers.
1 1 Century Central Building was built with only four floors, which was a rare high-rise building at that time. The walls of the tower are made of stone, and each floor should be able to bear the weight of each floor above. In order to make the tower stand, the wall at the bottom must be 5.2 meters thick. Buildings with load-bearing walls are up to 5 stories high. Because no matter how thick the bottom wall is, it can't support a higher structure. Only by using the frame to support the upper weight, coupled with the light wall to resist wind, frost, rain and snow, can a high-rise building be built. Medieval wooden houses were the first step in this direction. /kloc-in the 0/9th century, the output of steel increased greatly and its performance was reliable, and the fundamental solution was found.
The first load-bearing building with integral iron frame was a four-story houseboat built in Gines, England in 1860. Height16m, cast iron column, wrought iron beam, span 9m, bolted. But skyscrapers are made in America.
The first skyscraper with load-bearing frame is the 1884- 1885 Insurance Company Building in Chicago, which was designed by Jenny. The iron columns connected together in the lower six floors are wrought iron beam frames, and the upper four floors are steel frames. Since then, the United States has built steel-framed skyscrapers. As long as the frame is installed, all curtain walls of the whole skyscraper can be constructed separately on each floor at the same time, so the construction progress is very fast. Woolworths Building, a 55-story Gothic building in new york, took three years to build, with a height of 230 meters. 19 13 was the tallest building in the world when it was completed.
The Empire State Building in New York was completed several months later than the Woolworth Building, and the construction period was only 15 months. * * * The building is 102 floor and 375 meters high, which is a symbol of the rapid development of building technology in the 20th century. Sears Tower in Chicago, 1 10 floor, 473 meters high, was completed in 1973. At present, there are1.20 thousand people working in it, and the total floor area of each floor is 4 1.4 hectares, which is 100 times the floor area of the bottom floor.
