“…However, appropriate bond-slip laws capable to predict the structural behavior of strengthened RC elements are not yet available in the literature for inorganic based strengthening systems. Nevertheless, the reliability and adaptability of some bond-slip laws [33][34][35][36] proposed for the FRP systems to predict the behavior of RC beams externally simple plated with SRG and SRP systems was recently analyzed by Bencardino and Condello [23]. The study concludes that among a set of bi-linear FRP-concrete bond-slip laws, the Lu et al [35] bond-slip model was also suitable to simulate the behavior of a SRG-concrete interface.…”

Abstract:The purpose of this study is to evaluate, through a nonlinear Finite Element (FE) analysis, the structural behavior of Reinforced Concrete (RC) beams externally strengthened by using Steel Reinforced Grout (SRG) and Steel Reinforced Polymer (SRP) systems. The parameters taken into account were the external strengthening configuration, with or without U-wrap end anchorages, as well as the strengthening materials. The numerical simulations were carried out by using a three-dimensional (3D) FE model. The linear and nonlinear behavior of all materials was modeled by appropriate constitutive laws and the connection between concrete substrate and external reinforcing layer was simulated by means of cohesive surfaces with appropriate bond-slip laws. In order to overcome convergence difficulties, to simulate the quasi-static response of the strengthened RC beams, a dynamic approach was adopted. The numerical results in terms of load-displacement curves, failure modes, and load and strain values at critical stages were validated against some experimental data. As a result, the proposed 3D FE model can be used to predict the structural behavior up to ultimate stage of similar strengthened beams without carrying out experimental tests.

“…For this reason the numerical simulations were carried out taking into consideration bond-slip laws proposed for FRP systems. Several FRP-concrete bond-slip laws are available in literature [32][33][34][35][36][37][38]. In this study the bond-slip laws with a simple bi-linear shape (summarized in Table 2) were considered and analyzed [32,34,35,37].…”
