This paper aims to evaluate the reliability indexes of reinforced concrete beams designed in accordance with brazilian code NBR-6118:2014 in relation to the ultimate limit state of flexure. The main statistics of the resistance model are obtained through Monte Carlo simulation using ANSYS software and its probabilistic design tool. The reliability indexes are evaluated by FORM, being performed a parametric study in order to assess the influence of the main design variables on the safety level
