  2. Rebar - Wikipedia

    en.wikipedia.org/wiki/Rebar

    Rebar (short for reinforcement bar or 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.

  3. Reinforced solid - Wikipedia

    en.wikipedia.org/wiki/Reinforced_solid

    The table below shows computed reinforcement ratios for 10 stress tensors. The applied reinforcement yield stress is = 500 N/mm². The mass density of the reinforcing bars is 7800 kg/m 3. In the table is the computed brittle material stress.

  4. Rebar spacer - Wikipedia

    en.wikipedia.org/wiki/Rebar_spacer

    A rebar spacer is a short, rod-like device used to secure reinforcing steel bars, or rebar, within cast assemblies for reinforced concrete structures. The rebar spacers are fixed before the concrete is poured and remain within the structure. The main categories of rebar spacers are: Linear Spacers (Section profiles, H-section profiles, or 3 ...

  5. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_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.

  6. Reinforced concrete column - Wikipedia

    en.wikipedia.org/wiki/Reinforced_Concrete_Column

    ACI Code 7.10.4.2: For cast-in-place construction, size of spirals shall not be less than 3/8 in. diameter. ACI Code 7.10.4.3: Clear spacing between spirals shall not exceed 3 in., nor be less than 1in. Section 10.9.3 adds an additional lower limit to the amount of spiral reinforcement via the volumetric spiral reinforcement ratio ρ s.

  7. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).

  8. Precast concrete lifting anchor system - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete_lifting...

    The configuration (size, position and quantity) of this reinforcement should be supplemented to the element reinforcement design to ensure for adequate capacity of the lifting design. Lifting design is influenced by the steel / concrete interaction of the specific anchor selected. Different load cases are considered by the lifting design ...

  9. Anchorage in reinforced concrete - Wikipedia

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

    Reinforced concrete is concrete in which reinforcement bars ("rebars"), reinforcement grids, plates or fibers are embedded to create bond and thus to strengthen the concrete in tension. The composite material was invented by French gardener Joseph Monier in 1849 and patented in 1867. [1]
