  2. Rebar - Wikipedia

    en.wikipedia.org/wiki/Rebar

    Rebar (short for reinforcing bar), known when massed as reinforcing steel or steel reinforcement, [1] is a tension device added to concrete to form reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength.

  3. Reinforced concrete column - Wikipedia

    en.wikipedia.org/wiki/Reinforced_Concrete_Column

    Reinforced concrete column. (Redirected from Reinforced Concrete Column) A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.

  4. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    The Salginatobel Bridge is an example of this. Concrete cracks due to tensile stress induced by shrinkage or stresses occurring during setting or use. Various means are used to overcome this. Fiber reinforced concrete uses fine fibers distributed throughout the mix or larger metal or other reinforcement elements to limit the size and extent of ...

  5. Mechanical connections - Wikipedia

    en.wikipedia.org/wiki/Mechanical_connections

    Mechanical rebar connections, also known as mechanical splices or mechanical coupler, are used to join lengths of rebar together to transfer forces from one steel rebar to another. [1][2] Mechanical couplers can be advantageous in comparison with conventional methods of lap splicing because of the requirement for less steel for overlapping.

  6. 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.

  7. Concrete cover - Wikipedia

    en.wikipedia.org/wiki/Concrete_cover

    Concrete cover. Concrete cover, in reinforced concrete, is the least distance between the surface of embedded reinforcement and the outer surface of the concrete (ACI 130). The concrete cover depth can be measured with a cover meter. The purpose of concrete cover is to protect the reinforcement from corrosion, fire, and other potential damage.

  8. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete

    Tensile strength (σt) Stronger than concrete. Reinforced concrete, also called ferroconcrete, is a composite material in which concrete 's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.

  9. Banach fixed-point theorem - Wikipedia

    en.wikipedia.org/wiki/Banach_fixed-point_theorem

    Banach fixed-point theorem. In mathematics, the Banach fixed-point theorem (also known as the contraction mapping theorem or contractive mapping theorem or Banach–Caccioppoli theorem) is an important tool in the theory of metric spaces; it guarantees the existence and uniqueness of fixed points of certain self-maps of metric spaces and ...
