  2. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    A slab is ground-bearing if it rests directly on the foundation, otherwise the slab is suspended. [3] For multi-story buildings, there are several common slab designs (see § Design for more types): Beam and block, also referred to as rib and block, is mostly used in residential and industrial applications. This slab type is made up of pre ...

  3. Reinforced concrete column - Wikipedia

    en.wikipedia.org/wiki/Reinforced_Concrete_Column

    Reinforcing rebar is placed axially in the column to provide additional axial stiffness. Accounting for the additional stiffness of the steel, the nominal loading capacity P n for the column in terms of the maximum compressive stress of the concrete f c ' , the yield stress of the steel f y , the gross cross section area of the column A g , and ...

  4. Reinforced concrete structures durability - Wikipedia

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

    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 cement, carbon steel rebar) and with an expected service life of 50 years. Nevertheless, it is considered not completely exhaustive in some ...

  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. Grade beam - Wikipedia

    en.wikipedia.org/wiki/Grade_beam

    A grade beam or grade beam footing is a component of a building's foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. [1] It is used in conditions where the surface soil's load-bearing capacity is less than the anticipated design loads.

  7. Waffle slab foundation - Wikipedia

    en.wikipedia.org/wiki/Waffle_slab_foundation

    Waffle slab foundations adhere to International Building Code requirements. By 2008, most states put into effect the changes adopted in the 2006 IBC and, in regards to foundations, the on-grade mat foundation has become a more attractive design because, as an engineered system, it already accommodates the 2008 design recommendations, and required no major modifications to bring it into compliance.

  9. 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.
