Acesso em:.https://bdm.ufpa.br/handle/prefix/10369Prefabricated lattice stirrups are an alternative to conventional stirrups, with the potential to simplify reinforcement assembly and improve the construction process. This study experimentally investigated the shear strength of reinforced concrete continuous beams with prefabricated lattice stirrups, emphasizing the influence of supplementary reinforcement on the structural behavior and load-carrying capacity of the beams. Three beams were tested: a reference beam without transverse reinforcement, designated VR; a beam with prefabricated lattice stirrups, designated VW; and a beam with prefabricated lattice stirrups associated with supplementary reinforcement, designated VW+. The results indicated increases of approximately 76% and 132% in the shear strength of the VW and VW+ beams, respectively, compared with the reference beam. The VW+ beam exhibited improved crack control and greater mobilization of the transverse reinforcement, indicating that the supplementary reinforcement contributed to improving the anchorage conditions of the stirrups and limiting delamination mechanisms. The experimental strengths were also compared with the predictions of ABNT NBR 6118, ACI 318, and Eurocode 2. For the tested models, ABNT NBR 6118 Model I and ACI 318 provided conservative predictions, whereas ABNT NBR 6118 Model II and Eurocode 2 yielded nonconservative results. Under the evaluated conditions, the results indicated that the use of supplementary reinforcement can increase the efficiency of prefabricated lattice stirrups and improve the shear behavior of reinforced concrete continuous beams.Acesso AbertoArmadura de cisalhamentoArmaduras suplementaresVigas contínuasAncoragemDelaminaçãoResistência ao cisalhamentoGreenhouse GasesCarbon DioxideEnvironmental ImpactsWaterway TransportCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
