X-bracing
X-bracing is a structural engineering practice where the lateral load on a building is reduced by transferring the load into the exterior columns. X-bracing was used in the construction of the 1908 Singer Building, then the tallest building in the world. Some skyscrapers by engineer Fazlur Khan, such as the 1969 John Hancock Center The John Hancock Center is a 100- story, 1,128-foot supertall skyscraper located in Chicago, Illinois. Located in the Magnificent Mile district, the building was officially renamed 875 North Michigan Avenue in 2018. The skyscraper was designed ..., have a distinctive X-bracing exterior, allowing for both higher performance from tall structures and the ability to open up the inside floorplan (and usable floor space) if the architect desires.Ali Mir (2001), ''Art of the Skyscraper: the Genius of Fazlur Khan'', Rizzoli International Publications, References Structural engineering {{Engineering-stub ...

John Hancock Center
The John Hancock Center is a 100-story, 1,128-foot supertall skyscraper located in Chicago, Illinois. Located in the Magnificent Mile district, the building was officially renamed 875 North Michigan Avenue in 2018. The skyscraper was designed by Peruvian-American chief designer Bruce Graham and Bangladeshi-American structural engineer Fazlur Rahman Khan of Skidmore, Owings and Merrill (SOM). When the building topped out on May 6, 1968, it was the second-tallest building in the world after the Empire State Building, and the tallest in Chicago. It is currently the fifth-tallest building in Chicago and the thirteenth-tallest in the United States, behind the Aon Center in Chicago and ahead of the Comcast Technology Center in Philadelphia. When measured to the top of its antenna masts, it stands at . The building is home to several offices and restaurants, as well as about 700 condominiums, and at the time of its completion contained the highest residence in the world. The buildi ...

Structural Engineering
Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and muscles' that create the form and shape of man-made structures. Structural engineers also must understand and calculate the stability, strength, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and building services engineer and often supervise the construction of projects by contractors on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. See glossary of structural engineering. Structural engineering theory is based upon applied physical laws and empirical knowledge of the structural performance of different materials and geometries. Structural engineering design uses a number of relatively simple structural c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Singer Building
The Singer Building (also known as the Singer Tower) was an office building and early skyscraper in Manhattan, New York City. The headquarters of the Singer Manufacturing Company, it was at the northwestern corner of Liberty Street and Broadway in the Financial District of Lower Manhattan. Frederick Gilbert Bourne, leader of the Singer Company, commissioned the building, which architect Ernest Flagg designed in multiple phases from 1897 to 1908. The building's architecture contained elements of the Beaux-Arts and French Second Empire styles. The building was composed of four distinct sections. The original 10-story Singer Building at 149 Broadway was erected between 1897 and 1898, and the adjoining 14-story Bourne Building on Liberty Street was built from 1898 to 1899. In the first decade of the 20th century, the two buildings were expanded to form the 14-story base of the Singer Tower, which rose another 27 stories. The facade was made of brick, stone, and terraco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
