  2. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete

    In April 1904, Julia Morgan, an American architect and engineer, who pioneered the aesthetic use of reinforced concrete, completed her first reinforced concrete structure, El Campanil, a 72-foot (22 m) bell tower at Mills College, [21] which is located across the bay from San Francisco.

  3. Anchorage in reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Anchorage_in_Reinforced...

    Conventionally the term concrete refers only to concrete that is reinforced with iron or steel. However, other materials are often used to reinforce concrete e.g. organic and inorganic fibres, composites in different forms. While compared to its compressive strength, concrete is weak in tension. Thus adding reinforcement increases the strength ...

  4. Robert Maillart - Wikipedia

    en.wikipedia.org/wiki/Robert_Maillart

    Robert Maillart, c. 1925. Robert Maillart (16 February 1872 – 5 April 1940) was a Swiss civil engineer who revolutionized the use of structural reinforced concrete with such designs as the three-hinged arch and the deck-stiffened arch for bridges, and the beamless floor slab and mushroom ceiling for industrial buildings.

  5. Supply Depot (Toronto) - Wikipedia

    en.wikipedia.org/wiki/Supply_Depot_(Toronto)

    The Supply Depot is a unique example of Cold War military construction in Canada, with heavily reinforced concrete used to create a fortress-like structure designed to survive a nuclear blast. [1] The walls are 1.5 ft (0.46 m) thick, and the flat roof is a 2 ft (0.61 m) thick slab of exposed concrete supported by columns spaced 40 ft (12 m) apart.

  6. Tensioned stone - Wikipedia

    en.wikipedia.org/wiki/Tensioned_stone

    This method of construction is widely used for concrete structures, but the advantages of using similar techniques with stone are only just being realised.". [4] For concrete, this problem has been long solved: in addition to conventional tensile reinforcement, engineers developed prestressed concrete methods starting around 1888. Such tension ...

  7. History of structural engineering - Wikipedia

    en.wikipedia.org/wiki/History_of_structural...

    Wilhelm Ritter formulated the truss theory for the shear design of reinforced concrete beams in 1899, and Emil Mörsch improved this in 1902. He went on to demonstrate that treating concrete in compression as a linear-elastic material was a conservative approximation of its behaviour. [25]

  8. Reinforced concrete structures durability - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete...

    Once this is defined, design code gives standard prescriptions for w/c ratio, the cement content, and the thickness of the concrete cover. This approach represents an improvement step for the durability design of reinforced concrete structures, it is suitable for the design of ordinary structures designed with traditional materials (Portland ...

  9. Limit state design - Wikipedia

    en.wikipedia.org/wiki/Limit_state_design

    A clear distinction is made between the ultimate state (US) and the ultimate limit state (ULS). The Ultimate State is a physical situation that involves either excessive deformations leading and approaching collapse of the component under consideration or the structure as a whole, as relevant, or deformations exceeding pre-agreed values.
