  2. Portal frame - Wikipedia

    en.wikipedia.org/wiki/Portal_frame

    A portal frame steel building under construction. Portal frame is a construction technique where vertical supports are connected to horizontal beams or trusses via fixed joints with designed-in moment-resisting capacity. [1] The result is wide spans and open floors. Portal frame structures can be constructed using a variety of materials and ...

  3. Tube (structure) - Wikipedia

    en.wikipedia.org/wiki/Tube_(structure)

    Tube (structure) John Hancock Center in Chicago, designed in 1965 and finished in 1969, is an example of the trussed tube structural design. In structural engineering, the tube is a system where, to resist lateral loads (wind, seismic, impact), a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground.

    Animation depicting construction of multi-story building using aluminum handset formwork. Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then ...

  5. 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.

    (2) The thermal expansion coefficients of concrete and steel are so close (1.0 × 10 −5 to 1.5 × 10 −5 for concrete and 1.2 × 10 −5 for steel) that the thermal stress-induced damage to the bond between the two components can be prevented. (3) Concrete can protect the embedded steel from corrosion and high-temperature induced softening.

  7. Braced frame - Wikipedia

    en.wikipedia.org/wiki/Braced_Frame

    OCBF steel frame buildings originated in Chicago and reinforced concrete frames originated in Germany and France – areas where earthquakes were not an engineering consideration. [1] Accordingly, special concentrically or eccentrically braced frames were later developed with extensive design requirements, and are frequently used in areas of ...
