Numerıcal ınvestıgatıon on flexural behavıor of rc beams wıth large web openıng externally strengthened wıth CFRP lamınates under cyclıc load: Three-poınt bendıng test. Journal of Applied Engineering Science, 20(2), 570-580.1451-4117https://hdl.handle.net/20.500.12939/2527In the current paper, the effect of carbon fiber reinforced polymer (CFRP) laminates on the flexural strength of reinforced concrete beam (RCB) with the web opening in the flexural zone was investigated using a numerical method. The main aim of the current work is to model the reinforced concrete beam strengthen by two shape of CFRP laminates (2- layer and U-shape), to observe the influences of CFRP on the flexural strength of the beam. To this end, cyclic loading was applied to investigate the flexural behaviour of the Twelve RC beams under the cyclic loading. All beams kept the same dimensions length, breadth, and depth (2400 × 300 × 200) mm were modeled in the finite elements adopted by ABAQUS software. Steel bars have been used for both flexural strengthening and stirrups. A Three-point bending tests were performed using cyclic loading. Furthermore, the effect of web openings with different sizes (Side length of 40, 60, 75% of the breadth) on the flexural behavior of RC beams was investigated in detail. The flexural strength, local analysis, and ductility of the base beam and CFRP reinforced beam were analyzed. The results of the simulations revealed that the CFRP laminates enhanced the strength of the base beam significantly.eninfo:eu-repo/semantics/openAccessCarbon Fiber Reinforced PolymerCyclic LoadingFlexural BehaviorNumerical AnalysisReinforced Concrete BeamVon Mises StressYielding CriteriaArticle2025715812-s2.0-85131366801Q3
