  2. Reinforced concrete column - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Double tee - Wikipedia

    en.wikipedia.org/wiki/Double_tee

    The first building with all pre-stressed concrete columns, beams, and double tees was a two-story office building in Winter Haven, Florida, designed and built in 1961 by Gene Leedy. Leedy experimented when building his architectural office by using structural elements of prestressed concrete and designing the new "double-tee" structural ...

    The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3] The width of the solid area around the column should be 1 ⁄ 8 of the span between columns. Its height should be the same as the ribs. [3] Diagram showing waffle slab rib and Beam Heights rule of thumb formulas.

  5. Column - Wikipedia

    en.wikipedia.org/wiki/Column

    Modern columns may be constructed out of steel, poured or precast concrete, or brick, left bare or clad in an architectural covering, or veneer. Used to support an arch, an impost, or pier, is the topmost member of a column. The bottom-most part of the arch, called the springing, rests on the impost.

  6. Lally column - Wikipedia

    en.wikipedia.org/wiki/Lally_column

    A Lally column is a round or square thin-walled structural steel column filled with concrete, [1] and oriented vertically to provide support to beams or timbers stretching over long spans. Lally columns are an engineered component and as such must be installed exactly as the design engineer specified.

    Columns and entablature, structural elements that transmit, through compression, the weight of the structure above to other structural elements below. Columns are compression members . Subcategories

  8. T-beam - Wikipedia

    en.wikipedia.org/wiki/T-beam

    Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...

  9. Rebar - Wikipedia

    en.wikipedia.org/wiki/Rebar

    The US/Imperial bar size system recognizes the use of true metric bar sizes (No. 10, 12, 16, 20, 25, 28, 32, 36, 40, 50 and 60 specifically) which indicates the nominal bar diameter in millimeters, as an "alternate size" specification.
