From the United States to Asia and the Middle East, there are some impressive super-skyscrapers across the globe. Here is a run-down of the top-ten tallest towers in the world… 10. Two International Finance Centre, Hong Kong Completed in 2003, the Two International Finance Centre in Hong Kong is a stunning postmodern skyscraper with a futuristic glass façade. Standing at around 1,352 feet, it is one of only a handful of structures in the world housing double-decker elevators. 9. Willis Tower, Chicago Previously known as The Sears Tower, The Willis Tower in Chicago is the tallest building in the United States, standing at a height of 1,353 feet. The foundation stone of this 110-storey tower was laid in August 1970 and building was completed in 1973.

On the 103rd floor is a skydeck with unique protruding ledges which allow visitors to look down over the city of Chicago. 8. The Trump International Hotel, Chicago The Trump International Hotel in Chicago is a sleek glass structure measuring an impressive 1,362 feet. Comprising 92 storeys, it became the world’s second-tallest building when it was topped out in 2009. 7. The Jin Mao Building, Shanghai, China The Jin Mao Building in Shanghai, China, replaced King Tower as the tallest structure on the Shanghai skyline upon its completion in 1999. Measuring around 1,380 feet in height, this office, hotel and leisure complex has 88 storeys served by 130 elevators. 6. Guangzhou West Tower, China Standing at 1,444 feet tall, Guangzhou West Tower in Guangzhou, China, is a 103-storey super-skyscraper housing offices, hotels and a conference centre. Opened in 2010, the tower is to form part of the Guangzhou Twin Towers Complex when it is joined by Guangzhou East Tower, due for completion in 2016.

5. Greenland Financial Center, Nanjing, China Looming large over the skyline of Nanjing, the Greenland Financial Center in Nanjing, China, is a vast 1,476-feet-tall structure with 71 floors. Construction of this glass-clad building began in 2005 and was completed in 2010, when it was opened to the public as a hotel and office complex. 4. Petronas Towers, Kuala Lumpur, Malaysia Measuring over 1,483 feet, the Petronas Towers in Kuala Lumpur, Malaysia, were completed in 1998 and held the record for the world’s tallest skyscraper until 2003. Connected by a skybridge weighing a massive 750 tons on the 42nd and 43rd floors, the Petronas Towers remain the world’s tallest twin towers. 3. Shanghai World Financial Center, China At 1,614 feet, the Shanghai World Financial Center in China was envisaged to be a record breaker, surpassing the Petronas Towers to become the world’s tallest skyscraper.

Construction of the building began in 1997 but was interrupted for several years due to funding problems. By the time the structure was completed, work had already begun on Taipei 101, relegating the Shanghai World Financial Center to second place in the list of the world’s tallest buildings. 2. Taipei 101, Taiwan Located in the Hsin Yi district of Taipei in Taiwan, Taipei 101 broke the record for the world’s tallest structure in 2003 when an additional spire was fitted, completing the 1,676-foot Financial Center. With 91 floors, the building comprises offices, shops and is home to the world’s two fastest elevators. 1. Burj Khalifa, Dubai January 2010 saw the opening of the Burj Khalifa in downtown Dubai. Measuring an impressive 2,717 feet, the Burj Khalifa currently holds the title of the worlds tallest building. The skyscraper has 160 floors and is home to luxury apartments and hotels and fine restaurants, as well as offices and corporate suites.

Boasting both the tallest service elevator and the highest observation deck in the world, the Burj Khalifa is a real record breaker. Tall Buildings of the Future Proposals for new skyscrapers to be built in Eurasia and the Middle East may strip the Burj Khalifa of its status as the tallest freestanding structure in the world. Let’s take a look at two of the latest contenders for the world’s tallest building. Saudi Arabia is due to top the charts for the tallest building when The Kingdom Tower in Jeddah is completed. The proposed skyscraper is likely to measure around 3,280 feet in height, well over 550 feet taller than the Burj Khalifa. The Kingdom Tower is set to have an immense 275 floors and 59 elevators. It looks as if The Kingdom Tower will not enjoy its status as the world’s tallest skyscraper for long. In January 2012, it was revealed that plans are afoot for an immense tower, measuring over 1km tall, to be constructed as part of a new development on the Khazar Islands in Azerbaijan.

Due for completion in 2019, The Azerbaijan Tower will measure approximately 3,440 feet and is likely to have some 189 floors. 3k Petronas Twin Towers - World's tallest buildings, monuments and other structures - Pictures - CBS News World's tallest buildings, monuments and other structures Next Yokohama Marine Tower Considered to be the world's tallest lighthouse - though there are disputes over the qualifications of "lighthouse" - the Yokohoma Marine Tower stands at 348 feet and is located in Yokohama, Japan.

Credit: Wikimedia Illumin - The Petronas Towers Tags: building & architecture The Petronas Towers in Kuala Lumpur, Malaysia are not only some of the world's tallest buildings, but also give insight into the advancements of architectural technology.

Both the obvious and obscure elements of this structure illustrate its role as a precedent for skyscrapers of the future. The buildings are marveled not only for their great height but also for their practicality and usability. Primarily used for office space, these buildings are examples of the ever-changing workplace. The combination of the towers' architectural design and structure, integrated with its communications and security systems, demonstrate the significance of engineering in all aspects of its production. Background on the Towers Sagum/Wikimedia Commons Figure 1: The Petronas Towers tower over the city of Kuala Lampur at 378 meters in height. Completed in 1997, each of the Petronas Towers rises to 378 meters in 88 stories and contains over 4.6 million square feet (Fig. 1) [1]. Because of the pinnacles that sit atop each tower, their total height is 452 meters, surpassing Chicago's Sears Tower by about 10 meters, thus giving the Petronas Towers the title of the tallest buildings in the world as of 2001.

[Editor's Note: At the time of this article's publication, the Petronas towers were the tallest buildings in the world. In 2010, the Burj Khalifa replaced the Petronas Towers as tallest buildings, standing at 828 meters.] The towers are connected at floors 41 and 42 by a two-story sky bridge, which spans 58.4 meters and rises 170 meters above the ground [1]. The structures are used primarily for office space and are home to Petronas, Malaysia's state-owned oil company, and other international corporations. The buildings also contain a concert hall for the Malaysian Philharmonic Orchestra in addition to two Muslim prayer rooms. The buildings took over five years to complete with construction costs topping 800 million dollars. Exterior Design The towers were designed by the architectural firm of Cesar Pelli and Associates. Due to the prevalent Islamic culture of Malaysia, Pelli chose a geometric pattern common to Muslim heritage. The pattern consists of two rotated squares, with circle infills where the squares intersect. This geometric figure has been described by architects as symbols of "unity, harmony, stability and rationality - all important principles of Islam" [1].

The circular pattern rises consistently to the top of the building, while getting smaller and smaller in circumference. There are also two smaller, 40-story circular bustles attached to each building for additional office space. Construction of the Towers After the initial design by the architects, structural engineers were called in to determine how the structures were to be actually built. This process included deciding on the building site, what materials to use, and the method of construction. Before construction began, the structural engineers performed site tests to ensure that the buildings, which had an estimated weight of over 300,000 metric tons, would have a good foundation. During these examinations, they found that the original site contained an underground cliff that made it unsuitable for building. With extra work and expense, the towers could have been built on this site, but the engineers predicted that in years to come, the towers would begin to tilt. They then decided on a site, 60 meters southeast of the original, where they could develop a more stable, uniform foundation [2]. Each building's foundation was set from 55 to 130 meters underground and contained individual supports surrounded by a mixture of sand and cement.

The supports were then filled with a concrete mixture created especially for this project. This concrete was continuously poured for over 52 hours to ensure stability and a smooth finish. The process of excavating the site and laying the foundation took about a year to complete [3]. Subsequent to the foundation being set, construction on the towers began. Since constructing a tower this tall was new ground for the contractors involved, they were forced to use new ideas to aid in their task. They employed the Global Positioning Satellite system, the first ever used in Malaysia, "... to calculate the accuracy of the towers' vertical height" (Kiat).They also made use of computer technology "...which integrated and coordinated the mechanical, electrical and structural architectural drawings..." made by the contractors [3]. Instead of employing the conventional steel framework used in most skyscrapers, structural consultants opted for concrete. The designers realized that steel structures tended to be more flexible whereas the stiffer concrete would be more suitable for the job. Since the architect wished for tall, slender buildings, a new concrete, three times stronger than any other concrete used in construction, was developed and successfully deployed [2]. Steel was not completely left out of the building process, though.

The buildings' floor beams were made from steel in order to minimize height and accommodate mechanical equipment, such as cooling ducts [2]. Construction of the Sky Bridge The sky bridge was inserted at the buildings' forty first and forty second floors to ease travel between the towers due to their magnificent heights. This was one of the most structurally challenging parts of construction because the bridge had to be built on the ground and then lifted into place. The sky bridge's design was crucial to its safety and endurance. If not built accurately, the bridge could succumb to high winds or seismic activity. It was also imperative that the towers were in perfect symmetry so that the bridge would be positioned correctly. Lifting the bridge into place was a slow and tedious 32-hour task. The construction firm responsible for setting the bridge into place, VSL Heavy Lifting, conducted studies in both the United States and South Korea simulating wind and weather conditions that would affect the lifting of the bridge. After a year of preparation, the company was ready to raise the bridge. Pieces of the bridge were elevated from the ground by cranes and from above by lifting jacks. The hinges of the bridge were assembled first and then the framework for the rest of the bridge was set in place.

The bridge's 325-ton center section was raised at a speed of 12 meters per hour to ensure that it would not be dropped. The pieces of the bridge were then secured together and construction was complete. The bridge is supported by a two-hinge arch system with each hinge extending from its respective building's twenty ninth floor to the center of the bridge, forming an arch. Spherical bearings were placed at the end of each hinge and at the center of the arch where the hinges meet to allow for movements of the buildings. This is to prevent a build-up of tension in the hinges in the case of heavy winds. For instance, if the buildings are swaying in different directions, the hinges will twist on the bearings, keeping the bridge steady and in place while the buildings move [1]. Elevator System In office buildings the size of the Petronas Towers, it is important that there be an efficient elevator system that can handle the large numbers of people that use the elevators simultaneously. Since the towers are each 88 stories high, it is inefficient in terms of money, space, and time to have single elevators traveling directly from the bottom to the top of the building.

This prompted the builders to design high-speed double-deck elevators. The organization of double-deck system involves two elevators occupying one elevator shaft, but servicing different floors. The bottom elevator travels from the ground floor to the sky lobby on the forty first floor, while the top shuttle services floors 42 through 88. To further increase effectiveness, the elevators each carry 26 people and are designated to service only even or odd numbered floors. With each tower boasting 29 double-deck elevators moving at speeds between 3.5 and 7 meters per second, there are shorter waiting times and less traffic. When building these shuttles, the designers were concerned with speed along with the effects that such elevators have on passengers. Studies have shown that during long descents, high-speed elevators can cause earaches, and, therefore, the elevators' speed should not exceed 2000 feet per minute [4]. Designers have also learned that if an elevator has been stationary for a while, high winds that cause the building to sway can also have an adverse effect on the elevator's cable system.

The movements of the building "...can amplify traveling cable and compensation rope movements to problematic levels," providing a bumpy, uncomfortable ride for passengers [4]. Engineers of the Petronas Towers avoided this problem by designing the buildings to withstand high winds. Communications and Security Systems Because the Petronas Towers are mainly made up of businesses and corporate organizations, a good communications system is vital to productivity. Computer engineers working on the project helped design a cabling system, which allows for inter-building communication as well as the ability to connect to outside telecommunications carrier companies [1]. The on-site Central Telecommunications Office (CTO) controls all of the communication needs within the building and connects the building to the outside world. The speed of information transmission was also a concern; therefore, the CTO was connected to multiple exchange routes and carrier providers. This is to ensure that the network will not crash or significantly slow down when there is a lot of traffic. The CTO provides users with video conferencing, e-mail, and telephone services. It also connects the buildings' computers to a high-speed fiber optic network, which handles state-of-the-art information technology applications [1]. That same type of technology is also used in the buildings' security system.

The system operates through a local area network (LAN), which is a network of computers that control different aspects of the system and link the information gathered. The security system's activities are coordinated by high-level software that collects and stores data from the sub-systems. These sub-systems include a card access system, voice intercoms, alarm monitoring system, audio alarm surveillance system, closed-circuit television, and photo identification system [1]. Effect on Industry Though the towers took years to complete, their reign as the world's tallest buildings may be shorted lived. The buildings' construction sparked a worldwide competition to build a taller structure. Plans for taller buildings in both Taiwan and China are in the works and may be completed in the near future [5]. The new concrete developed for the project also had a positive effect on the international construction industry. Malaysian builders have now realized that using this material allows them to construct buildings faster and with less expense [2]. Also, new high-rises going up around the world use this new, strong concrete in place of steel. Construction of the Petronas Towers demonstrates that more goes into designing and constructing a building than simply following architectural plans. There are structural and internal building concerns that warrant the aid of engineers.

Whether it be installing and maintaining computer systems or determining the sturdiest and safest way to construct the building, engineers are involved. References [1] "Petronas Twin Towers."

This bridge is the goal of tourists, who are the Petronas Towers with a limited number of tickets (approx. 1200 pieces). Beyond that the bridge is used also for the evacuation in emergencies in a tower, so that the inhabitants can move into the tower surely.

As is the case for other high buildings, the Petronas Towers could vary, if the wind so that the building of the bridge was not rigidly at a second tower installed. Among them there are Suria KLCC, which is one of the most encouraged shopping centres in Malaysia, and it is also the KLCC park, which a Joggingstrecke offers, Billard plays, and a playground for children as well as shows a pool with a jumping well symphonischen.

The development’s scope, scale, and design reflect the desire to create a representative manifestation of local traditions and ingenuity. In particular, the design is based on Islamic geometry, a reflection of Malaysia’s cultural heritage. The buildings are perhaps most noteworthy for the skybridge that connects them on the 41st and 42nd floors. Although there is no structural benefit to the connection, it offers more than just an architectural flourish. By linking the two buildings together, the facilities of each tower around that level can be shared, including a conference room, prayer room, and executive dining room. Additionally, the skybridge is an integral part of the towers’ fire evacuation strategy. Due to budgetary constraints, the development timeline of Petronas Towers was constrained to six years, an ambitious feat considering that the original expected construction time for the project was eight years. To speed things along, two construction consortiums were hired, each being responsible for building one of the towers. Naturally, incentives were established that rewarded the first team to the top with the rights to build the skybridge, resulting in a race between the Japanese and South Korean consortiums. Ultimately, Tower 2 was the first to reach its pinnacle, with the South Korean crew claiming victory.

Located in the hills of the southern Malay Peninsula, it is the nation's prinicipal economic, administrative, and cultural center. Manufactures include tin, rubber, and machinery and food products. Kuala Lumpur was founded by Chinese settlers in 1857 as a tin-mining camp. It expanded under British rule from 1873 to 1957 as a center of tin and rubber production. In 1895 it became the capital of the British-protected Federated Malay States. In 1957 it became the capital of the newly independent Federation of Malaya and remained the national capital when Malaysia was founded in 1963. Today that little tin-mining camp is home to the world's second (and third) tallest buildings, the Petronas Towers .

Zones Petronas Towers, Kuala Lumpur | Vinicius Design Petronas Towers, Kuala Lumpur 1 Reply The Petrona Towers also known as the Petrona Twin Towers, is a remarkable building in the city of Kuala Lumpur, the capital of Malaysia. They were considered the tallest building in the world for a couple of years since 1998 through 2004 until they were passed by the Taipei 101 a building in China. However the Petrona Towers are until today the tallest twin skyscrapers in the world, they are a landmark of the city of Kuala Lumpur. The towers were designed by an argentinian architect named Cesar Peli, the construction of the towers started in 1993 and were only finished in 1999. (1) There are some impressive characteristics about these skyscrapers, for example their overall height is 452 meters. Another interesitng concept behind this tower is that it did not have the purpose of becoming the tallest building in the world, its original purpose was to become landmark that demonstrated the commercial and cultural powers of the capital city.

This led to the creation of this twin towers that have various aspects of muslim architecture showing the cultural side of Kuala Lumpur. “In plan, an 8-point star formed by intersecting squares is an obvious reference to Islamic design” (2) As seen in this quote there are some characteristics that reference the Islamic architecture. (2) One of the most interesting aspects of the design of this two skyscrapers is the skybridge that are connecting both buildings. This not only facilitates the movement between both buildings but also has an aesthetic appeal. This skybridge is located on the level 41 and 42, the skybridge is of about 58 meters and weights about 750 tones. As we can see in the pictures there are also some arches that are supporting the bridge, at the top and at the bottom of this arches there are some rotational pins. According to the engineering behind the arches and the skybridge if the arcs were to fall the bridge would not fall but rather remain in its position.(3) Sources:
