Resumo: dc.description.abstractThe conventional technique of anchoring in reinforced concrete beam-column connections by simple adhesion with straight steel bars can result in extensive anchorage length, according to the amplitude of the requests, harming the economy and aesthetics of the architectural project by forcing the enlargement of the column. Known solutions for transferring stresses between steel and concrete include anchoring combined adhesion with mechanical devices: pins, hooks or bends. The design of the connections of structural elements is done by applying mathematical models proposed by the technical standards, whose different calculation methodologies can result in discrepancies in the predictive analysis of the anchorage resistance with potential impacts on the costs and safety of the building. This work investigates the factors that influence the resistant capacity of beam-column connections molded with right-angle bending bars, confronting the accuracy of the ACI 318 (2019) and NBR 6118 (2014) standards for estimating the resistance of the set to the stresses. After analyzing the test data collected in the specialized literature and comparing their results with the values ​​estimated analytically by the calculation models of the aforementioned standards, it was concluded that both codes meet the safety requirements, with the NBR being more conservative. The anchorage length proved to be the main factor influencing the anchorage efficiency, together with coverage and the compressive strength of the concrete.pt_BR
