Question

A reinforcement bar embedded in 2 concrete section which transfer stress and hold the sections

Answer 1

Explanation:

The reinforcement ratio in concrete beam design is the following fraction: The reinforcement ratio , ρ, must be less than a value determined with a concrete strain of 0.003 and tensile strain of 0.004 (minimum). When the strain in the reinforcement is 0.005 or greater, the section is tension controlled.

Various materials are used to reinforce concrete. Round steel bars with deformations, also known as deformed bars, are the most common type of reinforcement. Others include steel welded wire fabric, fibers, and Fm radio.

फोटो ही तो Reinforcement for concrete is provided by embedding deformed steel bars or welded wire fabric within freshly made concrete at the time of casting. The purpose of reinforcement is to provide additional strength for concrete where it is needed.
