迪拜的设计 土木专业英语翻译.doc

Design, Construction Structural Details of Burj Dubai Burj al Dubai - Now known as Burj Khalifa The goal of the Burj Dubai Tower is not simply to be the worlds highest building: its to embody the worlds highest aspirations. The superstructure is currently under construction and as of fall 2007 has reached over 160 stories. The final height of the building is 2,717 feet (828 meters). The height of the multi-use skyscraper will comfortably exceed the current record holder, the 509 meter (1671 ft) tall Taipei 101. The 280,000 m2?(3,000,000 ft2) reinforced concrete multi-use Burj Dubai tower is utilized for retail, a Giorgio Armani Hotel, residential and office. As with all super-tall projects, difficult structural engineering problems needed to be addressed and resolved. 迪拜塔的目的不仅仅只是成为世界上最高的建筑：而是象征着世界上最高的抱负。那个庞然大物目前正在建设当中，而到了2007年秋就已经超过了160多层。最后的高度将达到828米。这栋混合结构的摩天大厦将轻轻松松超过目前最高纪录的保持着台北101大厦。这栋拥有280000立方米混凝土的混合结构迪拜塔将投入商用，最为一个宾馆，商品房还有办公用所。和其他超高工程一样，复杂的工程意味着面临一大堆的工程问题要解决。 ? Structural System Description 结构系统说明： Burj Khalifa has refuge floors at 25 to 30 story intervals that are more fire resistant and have separate air supplies in case of emergency. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. 迪拜塔每隔25到30层便设置一个“避难层”，这些层跟普通楼层比起来更加能抗火而且备有独立的空气提供系统以防事故。钢筋混凝土结构使得它比全钢结构摩天大厦更坚实。 Designers purposely shaped the structural concrete Burj Dubai - Y shaped in plan - to reduce the wind forces on the tower, as well as to keep the structure simple and foster constructibility. The structural system can be described as a buttressed core (Figures 1, 2 and 3). Each wing, with its own high performance concrete corridor walls and perimeter columns, buttresses the others via a six-sided central core, or hexagonal hub. The result is a tower that is extremely stiff laterally and torsionally. SOM applied a rigorous geometry to the tower that aligned all the common central core, wall, and column elements. 设计者有意的将混凝土结构的迪拜塔设计成“y”形状的来减少风荷载对它的影响，同时也简化结构提高施工的可行性。结构系统
