Petronas Twin Towers
The Petronas Towers (), also known as the Petronas Twin Towers and colloquially the KLCC Twin Towers, are an interlinked pair of 88-storey supertall skyscrapers in Kuala Lumpur, Malaysia, standing at . From 1996 to 2004, they were the tallest buildings in the world until they were surpassed by the Taipei 101 building. The Petronas Towers remain the world's tallest twin skyscrapers, surpassing the original World Trade Center towers in New York City, and were the tallest buildings in Malaysia until 2021, when they were surpassed by Merdeka 118. The Petronas Towers are a major landmark of Kuala Lumpur, along with the nearby Kuala Lumpur Tower and Merdeka 118, and are visible in many places across the city. History and architecture The Petronas Towers' structural system is a tube in tube design, invented by Bangladeshi-American architect Fazlur Rahman Khan. Applying a tube-structure for extreme tall buildings is a common phenomenon. The 88-floor towers are constructed large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Tallest Buildings
This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least . Such definition excludes non-building structures, such as towers. History Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3,800 years until the construction of Lincoln Cathedral in 1311. The Strasbourg Cathedral in France, completed in 1439, was the world's tallest building until 1874. The first building considered to be a skyscraper was the Home Insurance Building, built in Chicago in 1885. The United States would remain the location of the world's tallest building throughout the 20th century until 1998, when the Petronas Towers were completed. Since then, two other buildings have gained the title: Taipei 101 in 2004 and Burj Khalifa in 2009. Since the beginning of the 21st century, the Middle East, China, and Southe ...

Qutb Minar
The Qutb Minar, also spelled Qutub Minar and Qutab Minar, is a minaret and victory tower comprising the Qutb complex, which lies at the site of Delhi's oldest fortified city, Lal Kot, founded by the Tomar Rajputs. It is a UNESCO World Heritage Site in the Mehrauli area of South Delhi, India. It was mostly built between 1199 and 1220, contains 399 steps, and is one of the most-frequented heritage spots in the city. After defeating Prithviraj Chauhan, the last Hindu ruler of Delhi before the Ghurid conquest of the region, Qutab-ud-din Aibak initiated the construction of the victory tower, but only managed to finish the first level. It was to mark the beginning of Islamic rule in the region. Successive dynasties of the Delhi Sultanate continued the construction, and, in 1368, Firuz Shah Tughlaq rebuilt the top parts and added a cupola. It can be compared to the 62-metre all-brick Minaret of Jam in Afghanistan, of , which was constructed a decade or so before the probable start o ...

Cross Section (geometry)
In geometry and science, a cross section is the non-empty intersection (set theory), intersection of a solid body in three-dimensional space with a Plane (geometry), plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections. The boundary of a cross-section in three-dimensional space that is parallel to two of the Cartesian coordinate system, axes, that is, parallel to the plane determined by these axes, is sometimes referred to as a contour line; for example, if a plane cuts through mountains of a raised-relief map parallel to the ground, the result is a contour line in two-dimensional space showing points on the surface of the mountains of equal elevation. In technical drawing a cross-section, being a Planar projection, projection of an object onto a plane that intersects it, is a common tool used to depict the internal arrangement of a 3-dimensional object in two dimensions. It is traditionally crosshatched with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muslim
Muslims () are people who adhere to Islam, a Monotheism, monotheistic religion belonging to the Abrahamic religions, Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God in Abrahamic religions, God of Abraham (or ''Allah'') as it was revealed to Muhammad, the last Islamic prophet. Alongside the Quran, Muslims also believe in previous Islamic holy books, revelations, such as the Tawrat (Torah), the Zabur (Psalms), and the Injeel (Gospel). These earlier revelations are associated with Judaism and Christianity, which are regarded by Muslims as earlier versions of Islam. The majority of Muslims also follow the teachings and practices attributed to Muhammad (''sunnah'') as recorded in traditional accounts (hadith). With an estimated population of almost 2 billion followers, Muslims comprise around 26% of the world's total population. In descending order, the percentage of people who identify as Muslims on each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Art
Islamic art is a part of Islamic culture and encompasses the visual arts produced since the 7th century CE by people who lived within territories inhabited or ruled by Muslims, Muslim populations. Referring to characteristic traditions across a wide range of lands, periods, and genres, Islamic art is a concept used first by Western culture, Western Art history, art historians in the late 19th century. Public Islamic art is traditionally non-Representation (arts), representational, except for the widespread use of plant forms, usually in varieties of the spiralling Arabesque (Islamic art), arabesque. These are often combined with Islamic calligraphy, Islamic geometric patterns, geometric patterns in styles that are typically found in a wide variety of media, from small objects in ceramic or metalwork to large decorative schemes in tiling on the outside and inside of large buildings, including mosques.

Fazlur Rahman Khan
Fazlur Rahman Khan (, ''Fazlur Rôhman Khan''; 3 April 1929 – 27 March 1982) was a Bangladeshi-American structural engineer and architect, who initiated important structural systems for skyscrapers. Considered the "father of Tube (structure), tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center. A partner in the firm Skidmore, Owings & Merrill in Chicago, Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century.Designing 'cities in the sky' Leh ...

Tube (structure)
In structural engineering, the tube is a system where, to resist lateral loads (wind, seismic, impact), a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground. This system was introduced by Fazlur Rahman Khan while at the architectural firm Skidmore, Owings & Merrill (SOM), in their Chicago office. The first example of the tube's use is the 43-story Khan-designed DeWitt-Chestnut Apartment Building, since renamed Plaza on DeWitt, in Chicago, Illinois, finished in 1966. The system can be built using steel, concrete, or composite construction (the discrete use of both steel and concrete). It can be used for office, apartment, and mixed-use buildings. Most buildings of over 40 stories built since the 1960s are of this structural type. Concept The tube system concept is based on the idea that a building can be designed to resist lateral loads by designing it as a hollow cantilever perpendicular to the ground. In the simplest incarnation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural System
The term structural system or structural frame in structural engineering refers to the load-resisting sub-system of a building or object. The structural system transfers loads through interconnected elements or members. Commonly used structures can be classified into five major categories, depending on the type of primary stress that may arise in the members of the structures under major design loads. However any two or more of the basic structural types described in the following may be combined in a single structure, such as a building or a bridge in order to meet the structure's functional requirements.Kassimali, A. (1999). ''Structural analysis''. 2nd edition. Pacific Grove, C.A.: PWS Publication. * Tensile structures: Members of tensile structures are subject to pure tension under the action of external loads. Because the tensile stress is uniformly distributed over the cross-sectional area of members, the material of such a structure is utilized in the most efficient ...
