With the advancement in engineering and technology, our world have seen a rise in the number of buildings built everyday for plenty of purposes. In the old era, the average building will have only one floor. But now we are seeing an average of six to ten floors in every buildings. Let’s take a look at the list of tallest buildings in the world.
Tallest Buildings In The World
1. Burj Khalifa
Presently the tallest building on the planet, Burj Khalifa opened at Dubai in January 2010 with a spectacular pyro technic display that highlighted the tower’s 2720 feet of steel and aluminum with almost 26,500 glass panels which were hand cut. The Burj Khalifa is far more taller than the nearest sky scraper that is Taiwan’s 1680 feet Taipei 101.

The height of the building has even exceeded ground cable anchored ultra tall radio antennas. Architectural vertical leap frogging however is not likely to cease with Burj Khalifa. Although the tower would be a real challenge to beat, it most likely will stay on top for a couple of years more only. Architects all over the world are planning to construct numerous new sky scrapers.
Some projects are still to materialize and leap off drawing boards, although plans for several record shattering towers have been dumped mid way on account of the world-wide economic slump over the last couple of years.
2. Burj Mubarak
This gargantuan structure rises to more than 3290 feet equivalent to 1001 metres. The height given in metres would be an allegory to a collection of South Asian and Middle Eastern folk tale classics, 1001 Arabian Nights states London architect Kuhne whose organization designed the structure. To cross the kilometre high mark or 3280 feet, the $8 billion Burj Mubarak would have 3 inter locked towers which support the over all structure.
The blades or towers pin wheel about a central triangular shaft that contains mechanical equipment and elevators. Each tower twists 50 degrees as the height increases for better strength and it expands a little at the top. The Kuwaiti land mark will therefore place more usable space and mass near its peak in comparison to other structures to prevent the building from having a very flexible or thin tip.
To reduce tower buffeting high altitude winds that might blow at 160 miles per hour, the Burj Mubarak will witness architectural placement of ailerons vertically placed, which are the horizontal flaps passengers on a flight witness on the plane wing’s trailing edge that assist in countering natural disturbances from gale force winds.
They look like a series of ribbons vertically running along the leading 6 edges of 3 blades. As the ailerons are continuously catching the sun and moving while they adjust sun light would reflect off of their surfaces. It will add a calm and soothing rippling reflection to the edge of the towers that will give a dynamic sparkle to this structure.
The 170 storeyed Miapolis rises to an altitude of almost 3500 feet at the Watson Island in Biscayne Bay, east downtown Miami and west Miami Beach. The $23 billion Miapolis building will include a marina, office space, indoor amusement park, performing arts center, and luxury apartments and condos. At Miapolis the designers are hoping to demonstrate economic potential benefits of high-profile real estate.
The planners and the developers state it could bring in over a billion in yearly tax revenue and pump more than thrice that in to the local economy as visitors throng South Florida to check out the newest international tourist attraction. But for now, the project is yet to jump out from the artist’s drawing board at the architectural organization Karp Kobi.
There is no dearth of artistic impression of the many sides of the ambitious Miapolis structure. The developers want the structure to be environmentally friendly and plan to have the structure receive a platinum LEED rating through the United States Green Building Council.
More information about the enterprising Miapolis project is trickling in as right now designers are a little tight-lipped when interviewed regarding the project, although chief developer Socarras states he will be announcing fresh details in a couple of weeks.
In the mean time, Socarras is in discussion with the Aviation Federal Administration for getting clearance for the planned Miapolis’ extreme height taking into consideration the proximity of Miami International Airport to the proposed site.
4. Nakheel Tower
This cylinder shaped mega tower has 8 spires that meet at a point at the structure’s peak. Although an officially designated height had not been revealed, Nakheel Tower is most likely to cross almost 3300 feet. Its chief architects and designers, the global company Woods Bagot have ambitious plans for the Tower to be the true first materialization of a vertical oriented city.
Over 16,000 people will work, live and socialize in this tower with a ground foot print the dimension of a New York city’s square block. Placement of support columns is based on a symmetrically radial 18 point star pattern that is inspired by Arabic patterns. This pattern does make sense from an engineering perspective as a symmetrical structure supports the load in a balanced way among the structural units.
The most challenging part about designing and constructing the Nakheel Tower based on a study was dealing with wind vortex shedding that can cause structure damaging vibration. Rather than funneling wind around its glass and metal skin, Nakheel Tower takes the unusual approach of having huge gaps in the middle of the structure with a dual set of slots that lets gale winds to pass through harmlessly.
For every 28 floors, large disc like sky bridges are utilized to bind the towers together and serve as socializing squares for high-rise dwellers. The Nakheel Tower’s completion date has been postponed on account of market conditions being unfavorable; although some initial construction work did get under way.
5. Sky City 1000
Takenake Corporation came up with the proposal for Sky City 1000 in the year 1990 to manage Tokyo’s population density issues. Congestion similar to the situation at Tokyo prompts a requirement for office space and green space that exceeds supply vastly. This also introduces a slew of social and environmental issues right from uncomfortably cramped commuter trains to pollution.
Takenake Corporation’s solution, build up, way up with placement of green spaces in between the structure. The gist of the proposal put forward was creating artificial land in the air stated Masato Ujigawa, chief manager, engineering at Takenaka Corporation. To accomplish this, Takenake Corporation will first begin with a base that is 1400 feet on each side, a foot print that is the equivalent of several city blocks.

Then as denoted by its name, Sky City 1000 will rise up a complete 1000 meters or 3280 feet consisting of 15 levels stacked on top of each another. Each level will function as its own town with a park like plaza in its centre surrounded by schools, residences and business. The building would contain 12,000 homes and be utilized to its full capacity by some 140,000 people.
Construction has not started on Sky City 1000 yet as Japanese population had started to shrink as of 2006. Notwithstanding, Ujigawa states that ideas originally intended for the Sky City 1000 project had since been utilized for more conventional construction projects.
These include but are not limited to concrete-reinforced carbon fibres rather than iron to reduce weight and self-sustained water service system in structures that treat sewage for reclaiming precious water.
6. Bionic Tower
The approximately $16 billion Bionic Tower breaks from conventional engineering principle introducing ground breaking radical design components for the 4030 fee tall tower, according to Celaya, architect, ECE Arquitecturas and 1 of 3 chief designers of Bionic Tower from Spain. Rather than a vertical foundation, Celaya has planned on a floating foundation similar to tree roots with a complex network of hundreds of anchors on the ground.
For supporting criss crossing pillars, the Bionic Tower draws inspiration through bird bones that are hollow and light, but strong and durable. The 12 stacked neighborhoods with in this vertical structure will get energy, water and other supplies through 95 vertical columns just like the phloem and xylem transport system with vascular plants that will serve as structural support also.
