Bond Slip Behavior of Reinforced Steel and Concrete
Journal Title: International Journal of Civil, Structural, Environmental and Infrastructure Engineering Research and Development (IJCSEIERD) - Year 2019, Vol 9, Issue 3
Abstract
The performance of bond behavior between steel and concrete in reinforced concrete structure is a major part in load transfer mechanism. The transfer of stress between reinforcement and concrete in the longitudinal direction of the bars is known to be bond. Bond strength is imperative in reinforced concrete, which means that load transfer and the structural behavior is achieved by the combination of two materials. Sufficient bond strength ensures that there is little or no slip between steel and concrete and helps in the safe transfer of stress between them. Anchorage of reinforcement depends on the bond between steel and concrete, crack width and crack spacing. Stiffness, deformation and dynamic behavior are also a function of bond. In this article the experimental investigations on bond strength is studied for M20 grade of concrete. Pull out test is carried out using universal testing machine, the load at a relative movement (slip) between steel and concrete at the free end of the bar is manipulated. The main objective of the study is to come out with a relationship between bond strength and different influencing factors affecting the bond strength as per IS 2770-1967.
