Diagrid
A diagrid (a portmanteau of diagonal grid) is a framework of diagonally intersecting metal, concrete, or wooden beams that is used in the construction of buildings and roofs. It requires less structural steel than a conventional steel frame. Hearst Tower in New York City, designed by Norman Foster, uses 21 percent less steel than a standard design. The diagrid obviates the need for columns and can be used to make large column-free expanses of roofing. Another iconic building designed by Foster, 30 St Mary Axe, in London, UK, known as "The Gherkin", also uses the diagrid system. British architect Ian Ritchie wrote in 2012: Buildings utilizing diagrid * Shukhov Tower in Polibino, Polibino, Russia (1896) * Shukhov Rotunda at the All-Russia exhibition, Nizhny Novgorod, Russia (1896) * Shukhov Tower, Moscow, Russia * Hearst Tower, New York, USA * 30 St Mary Axe, London, England * 1 The Avenue, Manchester, England * CCTV Headquarters, Beijing, China * The Bow, Calgar ...

Capital Gate
Capital Gate, also known as the Leaning Tower of Abu Dhabi, is a skyscraper in Abu Dhabi that is over tall, 35 stories high, with over of usable office space. Capital Gate is one of the tallest buildings in the city and was designed to incline 18° west, more than four times the lean of the Tower of Pisa, Leaning Tower of Pisa. The building is owned and was developed by the Abu Dhabi National Exhibitions Company. The tower is the focal point of Capital Centre.

Shukhov Tower
The Shukhov Radio Tower (), also known as the Shabolovka Tower (), is a broadcasting tower deriving from the Russian avant-garde in Moscow designed by Vladimir Shukhov. The free-standing steel diagrid structure was built between 1920 and 1922, during the Russian Civil War. History Design Vladimir Shukhov invented the world's first hyperboloid structure in the year 1890. Later he wrote a book, ''Rafters'', in which he proved that the triangular shapes are 20-25% heavier than the arched ones with a ray grating. After that, Shukhov filed a number of patents for a diagrid. He aimed not only to achieve greater strength and rigidity of the structure, but also ease and simplicity through the use of as little building material as possible. The first diagrid tower was built for the All-Russia Exhibition in Nizhny Novgorod in 1896, and later was bought by Yury Nechaev-Maltsov, a well-known manufacturer in the city. Shukhov was responsible for constructions of a new types of ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1 The Avenue
1 The Avenue is a building in Spinningfields, Manchester, England. It is situated on Deansgate adjacent to the Grade I listed John Rylands Library. Architecture The building consists of two mirror-image parallelograms, stacked one on top of the other, resulting in a three-storey cantilever on the east end of the building. The cantilever is supported by an inclined steel 'diagrid' structure. A diagrid is similar in shape to a triangle and other buildings have used a diagrid structure, such as 30 St Mary Axe in London. Reaction to the glass clad building has been mixed due its proximity to the Grade I listed Rylands Library which, along with Manchester Town Hall, is considered the finest piece of architecture in the city and one of the finest interpretations of Gothic revival Gothic Revival (also referred to as Victorian Gothic or neo-Gothic) is an Architectural style, architectural movement that after a gradual build-up beginning in the second half of the 17th century bec ...

Vladimir Shukhov
Vladimir Grigoryevich Shukhov (; – 2 February 1939) was a Russian and Soviet engineer-polymath, scientist and architect renowned for his pioneering works on new methods of analysis for structural engineering that led to breakthroughs in industrial design of the world's first hyperboloid structures, diagrid Thin-shell structure, shell structures, tensile structures, gridshell structures, oil reservoirs, Pipeline transport, pipelines, boilers, ships and barges. He is also the inventor of the Shukhov cracking process, first cracking method. Besides the innovations he brought to the oil industry and the construction of numerous bridges and buildings, Shukhov was the inventor of a new family of doubly curved structural forms. These forms, based on non-Euclidean hyperbolic geometry, are known today as hyperboloids of revolution. Shukhov developed not only many varieties of light-weight hyperboloid towers and roof systems, but also the mathematics for their analysis. Shukhov is part ...

Shukhov Tower In Polibino
The Shukhov Tower in Polibino, designed in 1896 by Russian engineer and architect Vladimir Shukhov, is the world's first diagrid hyperboloid structure. The tower is today located in the former estate of Yury Nechaev-Maltsov in the selo of Polibino in Lipetsk Oblast in Russia. History Vladimir Shukhov invented hyperboloid towers and was also the first one to use them in construction. For the 1896 All-Russia industrial and art exhibition in Nizhny Novgorod he built the steel diagrid tower, which became the first hyperboloid structure in the world. The hyperboloid steel gridshell attracted attention of European observers. In particular, the British magazine '' The Engineer'' published an article about the tower. After the exhibition closed, the openwork tower was bought by a leading glassware manufacturer and art sponsor, Yury Nechaev-Maltsov. It was relocated to his estate in Polibino where it has been preserved until now. The estate is currently under state protection ...

Shukhov Rotunda
Shukhov Rotunda (architecture), Rotunda was a round exhibition pavilion built for All-Russia Exhibition 1896 in Nizhny Novgorod, Russia. It was built in 1896 with a diagrid hanging cover (tensile gridshell – diagrid roof, Russian Empire patent No. 1894, dated March 12, 1899) and was the world's first Hyperboloid structure (in the center of the Rotunda). It is named after Vladimir Shukhov, who designed it in 1895. The Rotunda was high with a diameter of . The diameter of the steel Tensile structure, membrane was . The rotunda was subsequently moved to Yessentuki and demolished in the 1980s.

Steel Frame
Steel frame is a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper possible. Steel frame has displaced its predecessor, the iron frame, in the early 20th century. Concept The Rolling mill, rolled steel "profile" or cross section (geometry), cross section of steel columns takes the shape of the letter "". The two wide flanges of a column are thicker and wider than the flanges on a Beam (structure), beam, to better withstand compressive stress in the structure. Square and round tubular sections of steel can also be used, often filled with concrete. Steel beams are connected to the columns with bolts and threaded fasteners, and historically connected by rivets. The central "web" of the steel I-beam is often wider than a column web to resist the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Bow (Calgary)
The Bow is a skyscraper in downtown Calgary, Alberta, Canada. The 236 metre (774 ft) building was the tallest in Calgary between July 8, 2010, when it surpassed the Suncor Energy Centre, and May 11, 2016, when it was exceeded by Brookfield Place. The Bow is currently the second tallest office tower in Calgary and the third tallest in Canada outside Toronto. The Bow is also considered the start of redevelopment in Calgary's Downtown East Village. It was completed in 2012 and was ranked among the top 10 architectural projects in the world of that year according to ''Azure'' magazine. It was built for oil and gas company Encana, and was the headquarters of its successors Ovintiv and Cenovus. History Early plans EnCana Corporation (now Ovintiv), North America's second largest natural gas producer, announced plans for the high-rise in 2006. Early designs suggested that the project would consist of a complex of towers (perhaps two or more) over two blocks. The initial pr ...

CCTV Headquarters
The CCTV Headquarters is a 51-floor skyscraper formed out of a pair of conjoined towers that sits on the East Third Ring Road, Guanghua Road in the Beijing Central Business District (CBD) and serves as the headquarters for China Central Television (CCTV). Rem Koolhaas and Ole Scheeren of OMA were the architects in charge for the building, while Cecil Balmond at Arup provided the complex engineering design.
