Rebar (short for reinforcement bar or 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.
The reinforcement in a RC structure, such as a steel bar, has nothing to do with the anchrundergo? the same strain or deformation as the surrounding concrete in order to prevent discontinuity, slip or separation of the two materials under load. Maintaining composite action requires transfer of load between the concrete and steel.
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 .
Rebar is the most common form of concrete reinforcement. It is typically made from steel, manufactured with ribbing to bond with concrete as it cures. Rebar is versatile enough to be bent or assembled to support the shape of any concrete structure. Carbon steel is the most common rebar material.
The configuration (size, position and quantity) of this reinforcement should be supplemented to the element reinforcement design to ensure for adequate capacity of the lifting design. Lifting design is influenced by the steel / concrete interaction of the specific anchor selected. Different load cases are considered by the lifting design ...
In 1996, German university students created two concrete canoes using textile reinforcement. One boat utilized alkali-resistant glass as its textile reinforcement. To manufacture the glass in a fabric, a process called Malimo-technique was used to keep the glass in one continuous yarn, such that it could be used to make the fabric. The other ...
The calculation of reinforcement requirements for a one-way slab can be extremely tedious and time-consuming, and one can never be completely certain of the best design. [citation needed] Even minor changes to the project can necessitate recalculation of the reinforcement requirements. There are many factors to consider during the structural ...
The transformer consists of a primary coil which energises the circuit with an AC voltage and a secondary which is formed by a toroid of the concrete sample. The current in the sample is detected by a current coil wound around a section of the toroid (a current transformer). This method is good for measuring the setting properties of concrete ...
