چکیده:

For considering the design considerations and development of retrofitting of structures, exact identification of materials’ behavior and their interaction, is an important subject. In concrete structures that include a high percentage of existent and under constructionstructures, for calculation of anchorage length of bars and investigation of sufficiency of anchorage length of bars, the state of stress
distribution in bar and joint surface with concrete and their effective parameters areimportant. One of the important parameters in modeling the joint surface between bar and concrete is equivalent spring constant between two materials. Most researchers suggestexperimental test to obtain actual value of stiffness between two materials. In this study, for obtaining the exact values of stiffness, formulation on the base of equilibrium of elements and investigation of governing differential equations and experimental method were used. In experimental tests, slips and strains, pertinent to applying load were measured by strain gauges anddisplacement transducersthat were installed between 4 stations over concrete and bar surface with an acceptable accuracy
