Stirrup sample. Stirrups form the outer part of a rebar cage. The function of stirrups (often referred to as 'reinforcing steel links' and 'shear links') is threefold: to give the main reinforcement bars structure, to maintain a correct level of concrete cover, and to maintain an equal transferance of force throughout the supporting elements.

Concrete spalling from the ceiling of an office unit (interior) in Singapore, possibly due to rebar corrosion. Reinforced concrete can fail due to inadequate strength, leading to mechanical failure, or due to a reduction in its durability. Corrosion and freeze/thaw cycles may damage poorly designed or constructed reinforced concrete.
The rebar cages can also be installed inside printed concrete formworks in non-structural members, and the holes are filled with grout. This method of post-installed reinforcement has proven to be cost-effective; however, it requires attention to the interface between steel and the printed concrete. [12]
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.
Stirrup may also refer to: Baseball stirrups, a type of socks worn by baseball players; the braces supporting the lithotomy position utilised in medical examinations such as a pelvic exam; A clamp (tool) or support in the shape of a stirrup; Rebar bent in a loop and used to reinforce concrete; The stapes, a bone of the ear resembling a stirrup
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. While compared to its compressive strength, concrete is weak in tension. Thus adding reinforcement increases the strength ...
Three of the floating warehouses, designed for tropical warfare, have been built of concrete at National City, Calif., and cost $1,120,000 each. In the crew of the 265-ft. barges are 23 Army men. One concrete barge under tow by Jicarilla (ATF-104) was lost off Saipan during a typhoon , and another barge damaged the Moreton Bay Pile Light in ...
