BS 6744: Stainless steel bars for the reinforcement of and use in concrete. Requirements and test methods.

The reinforcement in a RC structure, such as a steel bar, has to undergo 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.
The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete.
Characteristics – Generally consisting of portland cement, water, construction aggregate (coarse and fine), and steel reinforcing bars , concrete is cheaper in comparison to structural steel. Strength – Concrete is a composite material with relatively high compressive strength properties, but lacking in tensile strength/ductility.
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.
A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [ 7 ] A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa ) and ultimate tensile strength of 58–80 ksi (400–550 MPa).
The reinforcement is directed in the x, y and z direction. The reinforcement ratio is defined in a cross-section of a reinforcing bar as the reinforcement area over the total area , which is the brittle material area plus the reinforcement area.
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 ...
