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, Calgary ...

Shukhov Tower
The Shukhov Radio Tower (russian: Шуховская башня), 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1 The Avenue
1 The Avenue is a building in Spinningfields, Manchester. 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 building 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 the Town Hall is considered the finest piece of architecture in Manchester and one of the finest interpretations of Gothic revival Gothic Revival (also referred to as Victorian Gothic, neo-Gothic, or Gothick) is an architectural movement that began in the late 1740s in England. The movement gained momentum and expanded in the first half of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Shukhov
Vladimir Grigoryevich Shukhov (russian: link=no, Влади́мир Григо́рьевич Шу́хов; – 2 February 1939) was a Russian Empire 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 shell structures, tensile structures, gridshell structures, oil reservoirs, pipelines, boilers, ships and barges. He is also the inventor of the 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 Tower In Polibino
The Shukhov Tower in Polibino is the world's first diagrid hyperboloid structure designed in 1896 by Russian engineer and architect Vladimir Shukhov. 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 (feder ...

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. Concept The rolled steel "profile" or 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, 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 higher bending moments that occur in beams. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
