In construction: Classification of structural systems The bundled tube, which consists of a number of framed tubes joined together for even greater lateral rigidity, begins to be practical at about 75 metres (250 feet). The foundation is reinforced by 380 piles, drilled down to 80m in the ground. The Sears Tower is constructed of nine steel “tubes”, each 75 feet across. The surface is divided into 110 apartments, 108 above ground, which is accessed with 104 elevators, 16 of which are double height. Willis Tower (formerly Sears Tower) consists of a structural steel frame that was pre-assembled in sections and then bolted in place on the site. (Khaleej Times, 2010), The Burj kahalifa has a system which collects moisture from the building’s air conditioning units and the water is reused to water the surrounding landscaping. - They form a soft tube. Taipei 101 was designed to give tenants the highest standard multifunctional environment, with the companies ABN AMRO, ING Insurance, KPMG and The Taiwan Stock Exchange use the tower as their headquarters. Daraus schließe ich: Mit Sears tower einen … (Ray Clancy, 2009), Taipei 101 not only has incredible technology but the construction of the 101 storey tower to represent growth and economical achievement in Taiwan, with breaking the record for the world tallest in which it is located in environment that experience typhoon and earthquakes. We analyzed a typical interior column and spread footing. The Burj Khalifa project is another step forward in meeting the, technological challenges of future construction and it set a new stage for the future generation of super-tall buildings. (Khan, 1976), In 2010, the tower was renamed from Sears tower to Willis Tower after Willis Group Holding is the largest tenant in the tower. For Herace Lin to win the bid, they organized a team supported by China Development Industrial Bank,Cathay Insurance, Shin Kong Insurance and China Insurance. (Ahmad Abdelrazag 2010). For instance, AEW Capital Management bought the building in 1994. RCH 631 Prof. Anne Nichols Structural Systems - Each tower is supported by a ring of 16 cylindrical columns placed on inner corners of star shaped plan. The light will be automatically dim in spaces depending on the amount sunlight entering through windows with light control system. Flat M2 The engineering design used for the towers to resist the wind is diverse in each tower. Steel shear plates are placed on the beam to create I-shapes beams, with shear studs attached in concrete section. Various tubes terminated at different level to further strengthen the bundled tubes at the center. On site, the units only needed bolted splice plate connections between beams and web bolted connections for the column splices. Tube structural system is when the structural is made tubes and number of tubes reduce in selective floor for example in willis tower on the 50th, 66th, 90th the number of tubes reduce by two or more. Therefore the Burj khalifa was built as an icon structure and to create more office space for businesses to move into Dubai. selection of equipment that has enough capacity to deliver concrete to the highest level, more than 160 floors up; design of a pipe line that can be installed with maximum construction efficiency; selection of equipment and pipe line system that work well with the site’s overall logistics and planning; maintenance of quality control of the pumping system and placement method by monitoring all components of the system and ensuring the concrete properties required. Hancock The Taipei tower has a central core, in every 8th floor horizontal trusses outrigger are connected to the central core. A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. The towers structure has been inspired by the baboon plant where the plant is very light and flexible but also very strong. Hence, their columns are more evenly stressed than in the single tube structure and their contribution to the lateral stiffness is greater. The sheikhs are inspired by ultra-modern architecture and engineering, where well known inland and offshore structures have been built for example palms island, Burj-al-Arab, emirate tower and ect.
