This paper studies the influence of the inclusion of a complementary vertical reinforcement on the ultimate resisted force in two pile caps with partially embedded socked with rough interface. The study is carried out through numerical simulations in the finite element software ABAQUS and comparisons with the experimental results obtained by Barros (2013). The parameters of Concrete Damaged Plasticity (CDP) are analyzed to calibrate the numerical model with the experimental data. In addition, the individual influence of each reinforcement bar of the caps under study is analyzed when added to the model, composing only the main longitudinal reinforcements of the cap. The results indicate that the inclusion of the complementary vertical reinforcement bars conferred an increase in the resistance to the ultimate force of the cap in the order of 2.03%.
