Deterministic analysis of strength and ductility of high-strength concrete columns

The study of stress-strain behavior of high strength concrete confined by transverse reinforcement has been widely considered by various researchers. As a result, various stress-strain relationships regarding columns made of high strength concrete have been presented. Since each suggested model is based on a limited number of experimental data of a researcher, it has often a good prediction on its experimental results but not on other data. In this study, all available models and experimental data presented by other researchers in the field of strength and ductility of columns made of high strength concrete have been collected. Based on the results of these studies and applying Operations Research(OR), an appropriate model is suggested. It is shown that the proposed model in comparison with other models has a very good agreement with experimental results, by using deterministic analysis.
