2. Anchor bolt - Wikipedia

   en.wikipedia.org/wiki/Anchor_bolt

   Anchor bolt. 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. Concrete cone failure - Wikipedia

   en.wikipedia.org/wiki/Concrete_cone_failure

   Concrete cone failure. Concrete cone is one of the failure modes of anchors in concrete, loaded by a tensile force. The failure is governed by crack growth in concrete, which forms a typical cone shape having the anchor's axis as revolution axis.

4. 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.

5. 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.

6. Rebar - Wikipedia

   en.wikipedia.org/wiki/Rebar

   Rebar (short for 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. Concrete is strong under compression, but has low tensile strength.

7. Dolos - Wikipedia

   en.wikipedia.org/wiki/Dolos

   A dolos (plural: dolosse[ 1 ]: 10) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod. Weighing up to 8 tonnes (8.8 short tons), dolosse are used to build revetments for protection against the erosive force of waves from a body of water. [ 2 ][ 3 ] The dolos was invented in 1963 ...
