    Research 2020 : October - December

    In this study, a nonlocal elastic rod model is applied to analytically evaluate the bond behavior between fiber-reinforced polymer\n(FRP) bars and engineered cementitious composites (ECCs). The second-order differential equation, which is based on nonlocal\nelasticity theory, governs the bond behavior of the FRP bars along the bond length. The classical elasticity model is a special case of\nthe nonlocal model. The solution of the second-order differential equation can be obtained by substituting three-stage linear bond\nstress-slip relationship of the FRP bars. The slip values (solution of the second-order differential equation) within the bond length\ncalculated by the nonlocal continuum rod model are affected by the nonlocal parameter e0a. The results from a case study show\nthat the maximum pullout force decreases when the nonlocal size effect is considered, thereby providing a closer approximation of\nthe experimental data than the existing local model.
