“…Recently, Biscaia et al (2013) have presented a load-displacement behavior model for bond-slip between FRP and concrete. Hawileh et al (2012) utilized interface cohesion element for modeling debonding of FRP plates using ANSYS program. They concluded that the developed finite element models are capable of accurately predicting and capturing capacity the debonding failure mode of RC beams strengthened with FRP plates.…”

“…Tension-only membrane SELL41 and elastic SHELL99 have also been used for this purpose Hawileh et al 2012). One possibility to better model FRP in ANSYS which is not tried previously by researchers (although used for modeling reinforcing bars in concrete, (Hunley and Harik 2012)) is to use its reinforced shells and solids elements.…”

The use of fiber reinforced polymer (FRP) composites in strengthening reinforced concrete beam-column subassemblies has been scrutinised both experimentally and numerically in recent years. While a multitude of numerical models are available, and many match the experimental results reasonably well, there are not many studies that have looked at the efficiency of different finite elements in a comparative way in order to clearly identify the best practice when it comes to modelling FRP for strengthening. The present study aims at investigating this within the context of FRP retrofitted reinforced concrete beam-column subassemblies. Two programs are used side by side; ANSYS and VecTor2. Results of the finite element modeling using these two programs are compared with a recent experimental study. Different failure and yield criteria along with different element types are implemented and a useful technique, which can reduce the number of elements considerably, is successfully employed for modeling planar structures subjected to in-plane loading in ANSYS. Comparison of the results shows that there is good agreement between ANSYS and VecTor2 results in monotonic loading. However, unlike VecTor2 program, implicit version of ANSYS program is not able to properly model the cyclic behavior of the modeled subassemblies. The paper will be useful to those who wish to study FRP strengthening applications numerically as it provides an insight into the choice of the elements and the methods of modeling to achieve desired accuracy and numerical stability, a matter not so clearly explored in the past in any of the published literature.

“…Different numerical studies, that take into account the partial interaction between CFRP reinforcement and substrate, based on 1D (see for instance [24]), 2D (see [25,26]) and 3D (see [27][28][29]) finite element formulations exist in literature. Partial interaction modeling is also considered in composite beams to take into account separately the behavior of both concrete slab and steel beam, see for instance [30,31].…”

“…Fiber reinforced polymer (FRP) laminates are widely popular in building construction for the strengthening of structural members (Kachlakev and Alsayed et al 2010;AlSalloum et al 2011;Elsanadedy et al 2012a, b;Alsayed et al 2014;Elsanadedy et al 2015Elsanadedy et al , 2016Shehab et al 2017). The influence of FRP laminates on the response of solid RC beams under flexure (Alagusundaramoorthy et al 2003;Ashour et al 2004;Hawileh et al 2013) and shear (Li et al 2001;Zhang et al 2004;Islam et al 2005) has been widely studied. However, the research on the use of FRP laminates in the strengthening of RC beams with opening is limited Abdalla et al 2003;El Maaddawy and Sherif 2009;Pimanmas 2010;Chin et al 2011;Hawileh et al 2012;Nie et al 2018).…”

This paper aims to investigate the behavior of fiber reinforced polymer (FRP) strengthened reinforced concrete (RC) beams containing large rectangular web openings in the flexure zone. Studied parameters were type of loading, opening size and strengthening scheme. Seven RC beams categorized into two different groups were tested. In the first group, two unstrengthened beams (one solid without opening and one with large rectangular web opening in the pure flexure zone) were tested under four-point bending. In the second group, five beams were tested under center-point loading. They comprised of one reference solid beam and four beams with large rectangular web opening in the maximum-moment region. Out of the four beams with openings, two specimens were unstrengthened and the other two were strengthened with two different FRP schemes. A numerical study was also conducted and the results of analysis were validated with experiments. The calibrated analysis was then used for some useful parametric studies in which the effect of different parameters was investigated.
