芝加哥South Wacker Drive大厦总高959英尺,它的结构费用为一亿一千万美元,工程将于1990年1月竣工。届时,它将以世界最高混凝土结构建筑称雄世界。该建筑集八十年代工程技术创新和后现代主义建筑艺术于一体。它设有混凝土框架哥德式玻璃园鼓屋顶,直径65英尺,高105英尺。在14层和17层内收,并从51层开始由六边形变化到八边形,这样不但摆脱了Meissan盒子模式,而且提供了更多光线充足的办公楼面。其饰面也打破了Meis-sian格调,框架饰面为粉红色花岗岩。在46层设置了电梯空中门廊,在这儿人员可转乘至32—45层或47—70层。其它各组电梯服务于2—17层和18—32层,还有两部施工电梯
The South Wacker Drive in Chicago has a total height of 959 feet. Its structural cost is US$110 million. The project will be completed in January 1990. By then, it will dominate the world with the world’s tallest concrete structures. The building integrates engineering technology innovation and postmodernism architectural art in the 1980s. It features a Gothic Glass Drum roof with a concrete frame, 65 feet in diameter and 105 feet high. On the 14th and 17th floors, advancing from hexagonal to octagonal from the 51st floor, this not only freed the Meissan box model, but also provided more light-filled office space. Its finish also broke the Meis-sian style, framed with pink granite. On the 46th floor there is an elevator air porch where people can transfer to 32-45 or 47-70 floors. Other groups of elevators serve the 2-17th and 18th-32nd floors, and there are two construction elevators
