高层建筑并非陌生的建筑。早在15世纪意大利中部建造起一幢私人高层住宅,这是高层建筑的萌芽。高层建筑真正进入发展阶段,还要从1883年美国芝加哥建造10层保险公司大楼算起。近百年来,其层数不断提高,五十年代以10至30层为多,六十年代建30至50层的不少,七十年代发展50至100多层,如纽约1972年建造了110层的超高层建筑——世界贸易中心。 High-rise buildings are not unfamiliar buildings. As early as the 15th century, a private high-rise residential building was built in central Italy, which is the sprout of high-rise buildings. The high-rise building really entered the stage of development, and it also counted on building a 10-story insurance company building in Chicago in the United States in 1883. In the past 100 years, the number of floors has continuously increased. In the 1950s, there were 10 to 30 floors. In the 1960s, there were a lot of 30 to 50 floors. In the 1970s, 50 to 100 floors were built. As in New York, it was constructed in 1972. Layer of high-rise buildings - World Trade Center.
