The behavior and load carrying behavior of reinforced concrete structures is influence by the interaction between the concrete and reinforcement. The stress transfer between reinforcement and concrete in the longitudinal direction of the bars is called bond. An essential feature of reinforced concrete is the bond between steel and concrete.

Bond Stresses in Steel-Concrete Interface
The longitudinal shearing stresses acting on the surface between steel and concrete are called bond stresses. These stresses arise due to the frictional resistance between steel and concrete, which prevents the slipping of steel within the concrete. The bond stresses are necessary for the transfer of forces between the steel and concrete, making the composite section act as a single unit.
Factors Affecting Bond Stresses
Several factors affect the bond stresses in steel-concrete interface, which include:
1. Surface Area: The bond stresses increase with an increase in the surface area of steel in contact with concrete.
2. Surface Condition: The bond stresses are affected by the surface condition of steel, which includes the presence of rust, scale, or oil.
3. Concrete Properties: The bond stresses depend on the compressive strength and stiffness of concrete. Higher concrete strength results in higher bond stresses.
4. Reinforcement Spacing: The spacing between the reinforcing bars affects the bond stresses. Closer spacing results in higher bond stresses.
5. Embedment Length: The bond stresses increase with an increase in the embedment length of the steel in concrete.
Conclusion
Bond stresses play a vital role in the behavior of steel-concrete composite structures. They ensure the transfer of forces between steel and concrete, making the composite section act as a single unit. Understanding the factors affecting bond stresses is essential for the design and analysis of steel-concrete composite structures.
