Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.

Question

How does the elastic modulus, Eu, can be determined?

Expert Solution

Step 1

Elastic modulus is also called as modulus of elasticity, it is the ratio of stress upon the longitudinal strain. The elastic modulus of an object can also be defined as it is the slope of its stress-strain curve in the elastic deformation region. The unit of elastic modulus is Pascal (Pa).
