Resumo:
Short reinforced concrete corbels are elements widely used in precast structures, projecting from pillars or walls to support other parts of the structure, with the function of redistributing efforts between the system. However, due to its loading conditions and geometry, there is a significant disturbance in the stress distribution along its cross section, so that its design cannot be carried out based on the general theory of bending, requiring the use of methods alternatives that produce satisfactory and safe solutions. Thus, this work sought to analyze theoretically and computationally three short corbels of concrete experimentally tested by KHOSRAVIKIA et al. (2018) through the Struts and Ties Method and the Finite Element Method, the first being based on the normative prescriptions of ABNT NBR 6118 (2014) and ACI 318 (2019) and the second method was analyzed using the ATENA software. In this way, the behavior of the models was verified regarding the estimation of resistance and failure modes in comparison with what was observed in the experimental, seeking to verify the safety of the models regarding the normative recommendations and the computational model.
