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. |
