“…The bond-slip model (Lu et al, 2005a) developed based on Lu et al (2005b) has been very widely accepted by the research community (e.g. Godat et al 2007;Smith and Gravina 2007;Obaidat et al 2010;Chen et al, 2012;). Lu et al (2006) later adopted a rotation angle crack model in conjunction with a user-defined constitutive model for concrete.…”

“…Recent developments in the use of these strengthening systems have heightened the need to carry out reliable numerical analyses based on the Finite Element (FE) method capable of predicting the behavior of strengthened structural elements at all stages of loading up to failure. There are numerous studies available in the literature regarding the numerical modeling of RC beams strengthened to shear and/or to flexure with FRP systems [4][5][6][7][8].…”

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.
