These setbacks were modeled in the wind tunnel to minimize wind forces.
As the tapering tower rises, setbacks occur at the ends of each “wing” in an upward spiraling pattern that decreases the mass of the tower as the height increases.
Khalifa tower windows#
The building’s Y-shaped plan provides the maximum amount of perimeter for windows in living spaces without developing internal unusable area. At the center of a new downtown neighborhood, Burj Khalifa’s mixed-use program focuses the area’s development density and provides direct connections to mass transit systems.īurj Khalifa’s architecture has embodied references to Islamic architecture and yet reflects the modern global community it is designed to serve. The Tower and its surrounding neighborhood are more centralized than any other new development in Dubai. By combining cutting-edge technologies and cultural influences, the building serves as a global icon that is both a model for future urban centers and speaks to the global movement towards compact, livable urban areas. Within a composite building’s primary structural elements.īurj Khalifa has redefined what is possible in the design and engineering of supertall buildings. Where known, the CTBUH database breaks out the materials used Examples include buildings which utilize: steel columns with a floor system of reinforcedĬoncrete beams a steel frame system with a concrete core concrete-encased steel columns Ĭoncrete-filled steel tubes etc. steel, concrete, timber) are used together in the main structuralĮlements. ForĮxample, a Steel Over Concrete indicates an all-steel structural system located on top of anĪll-concrete structural system, with the opposite true of Concrete Over Steel.Ī combination of materials (e.g. all-steel, all-concrete, all-timber), one on top of the other. Or concrete slab on top of timber beams is still considered an “all-timber” structure as theĬoncrete elements are not acting as the primary structure. Note that a building of timber construction with a floor system of concrete planks An all-timber structure may include the use of localized non-timber connections between Reinforced concrete which has been precast as individual components and assembled togetherįrom timber.
