The present work seeks to analyze the simplified procedures described in ABNT NBR 6118: 2014 for the design of slender columns of reinforced concrete. The standard presents the "Standard abutment method with approximate curvature" and "Standard abutment method with rough stiffness", which is intended for columns with slenderness> 90. The comparative studies of these methods found in the literature have divergent conclusions when it comes to choosing which method best fits the experimental results. Also discussed are proposals for improvements to methods for simplifying the sizing process. Finally, the authors present their conclusions about the methods studied.
