Super Highrise Building Technology

 Super Highrise Building Technology 

 

Super high rise buildings are supported by advanced structural analysis techniques and

materials technology. Super high rises towering over 200 m high were once constructed mainly as steel-frame structures. Now, many super high rises we see today use reinforced concrete, which excels steel-frame structures in constructibility and  economic efficiency. These buildings owe their structural excellence to the development of high-strength concrete technology whose st rength is several times higher than that of ordinary concrete. Concrete with very high strength featuring 80 to 130 N/mm2 is used in those new buildings under strict quality control. In addition, the CFT method, in which concrete is filled in steel columns to enhance compressive strength, was developed to achieve further economic super high rises. One of the outstanding technological element that support super high rises is earthquake resistant engineering, which is to be discussed in the next section. It makes very high buildings comfortable and safe living space by employing vibration damping structures, such as braces and reaction-generating pendulums to set off an external force due to seismic action or wind pressure.

nerated by, for instance, pendulums. Vibration damping is

One of today’s landmark super high rises (Table 1) is TAIPEI 101, the 509 m high world’s tallest building of steel CFT structure completed in November 2004 in Taipei,ROC. The world’s highest RC structure is the Petronas Twin Tower of 451.9 m high, completed in 1997 in Kuala Lumpur, Malaysia. Currently under planning in the UAE isa building over 700 m high
