2. Anchor bolt - Wikipedia

   en.wikipedia.org/wiki/Anchor_bolt

   Column-to-foundation connection [1] Anchor bolts are used to connect structural and non-structural elements to concrete. [2] The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.

3. Prestressed concrete - Wikipedia

   en.wikipedia.org/wiki/Prestressed_concrete

   Prestressed beam without load. Prestressed beam with load. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] It was patented by Eugène Freyssinet in 1928.

4. Utility pole - Wikipedia

   en.wikipedia.org/wiki/Utility_pole

   A pair of shoes can be seen hanging from the wires (center-left, far right) A utility pole is a column or post, usually made out of wood or aluminum alloy, [ 1 ] used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and street lights.

5. Retaining wall - Wikipedia

   en.wikipedia.org/wiki/Retaining_wall

   A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. [1]

6. Post (structural) - Wikipedia

   en.wikipedia.org/wiki/Post_(structural)

   Post (structural) A post is a main vertical or leaning support in a structure similar to a column or pillar, the term post generally refers to a timber but may be metal or stone. [1][2][3][4][5][6][7] A stud in wooden or metal building construction is similar but lighter duty than a post and a strut may be similar to a stud or act as a brace.

7. Structural support - Wikipedia

   en.wikipedia.org/wiki/Structural_support

   Structural support. A structural support is a part of a building or structure that provides the necessary stiffness and strength in order to resist the internal forces (vertical forces of gravity and lateral forces due to wind and earthquakes) and guide them safely to the ground. External loads (actions of other bodies) that act on buildings ...
