  2. Modified compression field theory - Wikipedia

    en.wikipedia.org/wiki/Modified_Compression_Field...

    The modified compression field theory (MCFT) is a general model for the load-deformation behaviour of two-dimensional cracked reinforced concrete subjected to shear. It models concrete considering concrete stresses in principal directions summed with reinforcing stresses assumed to be only axial.

  3. American Concrete Institute - Wikipedia

    en.wikipedia.org/wiki/American_Concrete_Institute

    The American Concrete Institute (ACI, formerly National Association of Cement Users or NACU) is a non-profit technical society and standards developing organization. ACI was founded in January 1905 during a convention in Indianapolis. [1] [2] The Institute's headquarters are currently located in Farmington Hills, Michigan, USA. ACI's mission is ...

  4. Concrete cone failure - Wikipedia

    en.wikipedia.org/wiki/Concrete_cone_failure

    The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.

  5. Mohr–Coulomb theory - Wikipedia

    en.wikipedia.org/wiki/Mohr–Coulomb_theory

    Mohr–Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Most of the classical engineering materials follow this rule in at least a portion of their shear failure envelope.

  6. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete

    Reinforced concrete structures are normally designed according to rules and regulations or recommendation of a code such as ACI-318, CEB, Eurocode 2 or the like. WSD, USD or LRFD methods are used in design of RC structural members. Analysis and design of RC members can be carried out by using linear or non-linear approaches.

  7. Shear strength - Wikipedia

    en.wikipedia.org/wiki/Shear_strength

    In structural and mechanical engineering, the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture or construction of the component (e.g. beams, plates, or bolts). In a reinforced concrete beam, the main purpose of reinforcing bar (rebar) stirrups is to increase the shear strength.

  8. 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]

  9. Strain partitioning - Wikipedia

    en.wikipedia.org/wiki/Strain_partitioning

    The partitioning of strain occurs through the development of a strike slip or shear zone (shown with red arrows) across the actively deforming region (brown).
