竣工年份: 2010年哈利法塔的建筑设计完美融合了当地文化元素与尖端技术，从而在极端沙漠气候条件下实现建筑的超高效能表现。作为综合体项目中的主体建筑，162层的哈利法塔包含办公空间、零售商区、住宅单位、以及一间阿玛尼（Armani）酒店。大厦的Y字型布局规划可以最大角度地饱览波斯湾的优美景致。一层空间被绿地环绕、辅以水景和适宜步行的林荫大道。大厦的整体造型灵感取自当地的沙漠之花蜘蛛兰的形态，以及伊斯兰建筑中的特殊几何图案装饰体系。哈利法塔采用钢筋混凝土加玻璃外墙结构，由多个大体量构筑物螺旋攀附带扶壁的中央核心筒而成。大厦从平坦的基座拔地而起，层层退台以螺旋状逐级上升，令大厦的体量随着高度的攀升而逐渐减小，中央核心筒最终在建筑的顶端显露出来，构成塔尖。SOM的建筑师与工程师以创新的策略出色地完成了挑战，筑就无可企及的高度。简洁的
Y字型布局不仅能显著降低风阻力，更能强化建筑的结构稳定性。Y型结构的每个支翼都拥有独立的高性能混凝土核心筒和外围环绕支柱，再与六边形的中央核心筒互相联结支撑，可提供极强的抗扭刚度。大厦的中央核心筒和支翼均按照严谨缜密的几何形态进行布置。每一层退台都与大厦的建筑网格完全匹配——这样的设计保证了所有支柱都与下方的承重墙对齐，提供更加直接和均匀的传力路径，避免施工时常见的立柱位移，确保施工的顺畅进行。大厦的宽度在每一层退台处得到削减。逐级内缩和逐步收窄设计的主要作用是“扰乱风力”，让整个建筑在每一个受风面的形状都不同，因此风力无法形成强大的漩涡。最重要的是，哈利法塔并非仅为达到某个特定高度而建，从长远而言，它的艺术性令它有别于其它摩天大楼，具有令人炫目的美学价值。哈利法塔不仅达到了，同时远远超越了这一标准。除了破纪录的高度之外，哈利法塔还通过全新、高效的结构体系和施工方法减少了材料用量和浪费。这些措施包括采用可将低湿度的冷空气从建筑顶部吸入的“高空取风”的通风系统。大楼还具有世界上最大的冷凝水回收系统之一。

The design for the Burj Khalifa combines local cultural influences with cutting-edge technology to achieve high performance in an extreme dert climate. As the centerpiece of a mixed-u develop
onlyyou歌词armageddonment, the tower contains offices, retail space, residential units, and a hotel. The Y-shaped floor plan maximizes views of the Arabian Gulf. At ground level, the skyscraper is surrounded by
green space, water features, and pedestrian-friendly boulevards.
The design for the tower is inspired by the geometries of a regional dert flower and the patterning systems embodied in Islamic architecture. Built of reinforced concrete and clad in glass, the tower is compod of sculpted volumes arranged around a central buttresd core. As it ris from a flat ba, tbacks occur in an upward spiraling pattern, which reduces the building’s mass as it reaches skyward. At the pinnacle, the central core emerges and is sculpted to form a spire.日你妈
SOM’s architects and engineers developed innovative strategies to meet the unique challenges of building a tower of unprecedented height. The simple Y-shaped plan reduces wind forces and also enhances constructability. Each wing, with its own high-performance concrete core and perimeter columns, buttress the others via a six-sided central core, or hexagonal hub. The result is a tower that is extremely stiff torsionally. The rigorous geometry of the design aligns all of the common central core and column elements.

The tbacks are organized in conjunction with the tower’s grid: the stepping is achieved by aligning
columns above with walls below to provide a smooth load path. This enabled construction to proceed without the typical delays associated with column transfers. At each tback, the building’s width changes. The advantage of the tower’s stepping and shaping is, in esnce, to “confu the wind.” Wind vortices can never coalesce becau the wind encounters a different building shape at each tier.Beyond its record-breaking height, the Burj Khalifa incorporates holistic strategies for mechanical, electrical, and plumbing (MEP) systems that make the building highly efficient, while minimizing environmental impact and reducing material usage and waste. Providing comfort and a healthy indoor environment were central goals. The high-performance curtain wall attenuates the summer heat and delivers superb radiant thermal comfort.
The team designed a “lifeboat” vertical transportation system with advanced monitoring and controls to provide easy egress during emergency events. The office pavilion integrates a backup system that can rve critical functions, such as supplying and draining water during a power outage. A “sky-sourced” ventilation system pulls cool, less humid air through the top of the building while employing one of the largest condensate recovery systems in the world.0
