Several numbers of strength models of FRP-confined circular concrete columns have been published by several researchers. In this study, strength models were proposed based on experimental data. Nine existing FRP-confined strength models of column confinement were reviewed in this study and two forms of strength models of FRP-confined circular concrete columns were proposed. The models were proposed based on different number of experimental data collected from literature. Based on the number of experimental data, i.e. 64-, 106-, 156- and 192-, the strength models were developed. The performance of the existing and the proposed strength models were evaluated and compared. The evaluation results showed that the strength models proposed based on 192-data had the best performance among other models proposed with smaller number of data. It was also shown that the proposed strength models had better performance than the existing strength models.
