Resumo
This work is about the reinforced concrete columns optimum design. It presents the formulations adopted for rectangular, circular, hexagonal and in “U” moderately slender sections design. It also covers slender rectangular sections in one direction. The design accords to Brazilian Code for procedures of concrete structures design, NBR 6118:2014. Thus, it comprises compressive strength concretes between 20 and 90 MPa. The developed computational program was implemented in the Matlab platform, and uses the Internal Point Method as an optimization algorithm. It gathers examples that attest the validity of the developed computational program, as well as verify the influences of certain characteristics in the design. The study indicates that the greater number of parameters released for optimization allows a considerable reduction in the total columns cost.
