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.
Rebar detailing is the discipline of preparing 'shop/placing' or 'fabrication' drawings or shop drawings of steel reinforcement for construction. Engineers prepare 'design drawings' that develop required strengths by applying rebar size, spacing, location, and lap of steel .
System identification and damage detection is a twofold area that utilizes ML to imitate a structural system and predict its deterministic seismic response. Laboratory tests of reinforced concrete (RC) structures have provided one source of data that enables ML methods to identify their failure modes, strength, capacities and constitutive ...
Fiber reinforcement is most often used to supplement or partially replace primary rebar, and in some cases it can be designed to fully replace rebar. [ 42 ] Steel is the strongest commonly available fiber, [ citation needed ] and comes in different lengths (30 to 80 mm in Europe) and shapes (end-hooks).
Reinforced concrete is concrete in which reinforcement bars ("rebars"), reinforcement grids, plates or fibers are embedded to create bond and thus to strengthen the concrete in tension. The composite material was invented by French gardener Joseph Monier in 1849 and patented in 1867. [1]
A Johnson bar (also Johnson corrugated bar) is a type of corrugated high-carbon steel [1] rebar used to reinforce concrete.. The Johnson bar was invented by A.L. Johnson [2] of the St. Louis Expanded Metal Company.
Rebar. Rebar is a steel bar or mesh of steel wires used in reinforced concrete and masonry structures to strengthen and hold the concrete in tension. The surface of rebar is often patterned to improve the quality of the bond with the concrete. Rebar is necessary to add tensile strength, while concrete is strong in compression. It can support ...
Concrete cover, in reinforced concrete, is the least distance between the surface of embedded reinforcement and the outer surface of the concrete (ACI 130). The concrete cover depth can be measured with a cover meter. The purpose of concrete cover is to protect the reinforcement from corrosion, fire, and other potential damage.
