Stress-strain relationships of experimentally tested RC columns under concentric loading are compared with the predictions of the Koksal model. Moment-curvature analyses of RC sections are also performed employing the same model in a self-developed moment-curvature program for confined concrete. Results are compared with the output of EXTRACT which uses the Mander concrete model. © 2011 WIT Press.eninfo:eu-repo/semantics/openAccessConcentric loading; Confinement; Reinforced concrete columns; Stress-strain relationsConference Object7217518310.2495/MC1101612-s2.0-84864858150Q3
