The objective of this work is to evaluate the nonlinear behaviour of beam elements of structural concrete, subjected to asymmetric bending, delimited by two consecutive sections of discontinuity (cracks or open joints), considering the variable adhesion model. For this, two algorithms were developed using the MATLAB tool from the numerical solutions presented herein. The first refers to the equilibrium of sections subjected to asymmetric bending. The second calculates the equilibrium of sections considering the bond-slip effect, maintaining the Bernoulli-Navier hypothesis where perfect adhesion is no longer possible. Two numerical applications (simply supported beams) are used to validate and verify the efficiency of the developed models and algorithms. Results obtained shown that there is a good agreement with the experimental results found in the literature, characterising a good alternative for the evaluation of the nonlinear behaviour of beam elements, when there is a loss of adhesion.

“…Yuan et al [29] conducted an experiment to investigate the bond-slip behavior of the FRP-concrete interface. In addition, Vilanova et al [30] performed a numerical simulation of bond-slip between the FRP and the reinforced concrete. According to the test results and the finite element results, Tekle et al [31] found that the distribution of bond stress between the GFRP bars and the alkali-activated cement was nearly uniform.…”

The article describes an experimental study on the bond–slip performance between the pultruded glass fiber-reinforced polymer (GFRP) tube and the nano-CaCO3 concrete. Taking the nano-CaCO3 concrete strength and GFRP tube thickness as primary parameters, nine specimens were designed and tested to study the influence of these parameters on the bond strength of the specimens. Besides, three specimens filled with the ordinary concrete were also tested by using the push-out tests to make comparisons with the bond performance of the specimens filled with nano-CaCO3 concrete. A total of four push-out tests were conducted on each specimen. The experimental results indicate that there are two types of axial load–slip curves for each specimen in four push-out tests. Moreover, comparison of the results of the push-out tests in the same direction shows that the bond failure load of the specimen decreases with the increase in the number of push-out tests. Based on the analysis of the test results, it is shown that the bond performance between the GFRP tube and the nano-CaCO3 concrete is better than that between the GFRP tube and the ordinary concrete. Furthermore, as the nano-CaCO3 concrete strength increases, the bond strength of the specimens decreases, indicating that the concrete strength has a negative effect on the bond strength. When the nano-CaCO3 concrete strength is relatively smaller (C20), the bond strength of the specimens decreases with the increase in the thickness of the GFRP tube. However, when the nano-CaCO3 concrete strength is relatively larger (C30 and C40), the bond strength of the specimens increases as the thickness of the GFRP tube increases.

“…Modelling strategy that implies direct inclusion of experimental bond-slip law was validated by 3D FE model [31], in terms of experimental deformation and cracking behavior. Lin and Zhang developed composite beam FE that accounts directly for the bond-slip effect [32], using the BPE (Eligehausen, Popov and Bertero) modified bond stress-slip model [33].…”

Modelling the bond in GFRP bar reinforced concrete thin structural members

This paper analyses the accuracy of FE (Finite Element) modelling of concrete thin slabs, reinforced with GFRP (Glass Fiber Reinforced Polymer) bars, under bending loading conditions. It considers two strategies of concrete/ bar interaction approachdirect and indirect. Indirect bond approach was combined with concrete tension stiffening model, whereas the direct bond one employed plain concrete constitutive model. Apart from selection of material and bond models, FE mesh sensitivity was examined. The efficiency of both bond modelling strategies was proven for the slab of standard thickness (100 mm) failed due to concrete crushing, whereas direct bond method was shown indispensable when simulating very thin slabs (40 mm) failed due to bar debonding.
