Shear keys are present in several precast elements, such as foundation sockets and beam-column
connections. In the literature, several analytical formulations are observed to predict its resistance. However, the
formulations do not consider the entire geometry of the shear keys. In this paper, numerical models in finite
elements were used with the software ABAQUS® to calibrate the shear keys tested by Zhou et al. (2005) and
Faleiros Júnior (2018). The influence of the key geometry and the concrete strength was evaluated through a
parametric analysis and compared with the analytical formulations. The results showed which geometric
parameters have more influence on the strength of the keys. Furthermore, the results indicated that analytical
formulations are inappropriate for some geometries.
