While earlier research has used sparse and imprecise data to study the load-carrying capacity
(LC) prediction of fiber-reinforced polymer (FRP)-confined concrete-filled steel tube (CFST) compression
members (SFC), no study has examined the predictive accuracy of different modeling approaches using an
extensive and refined database. The purpose of this work is to present an analytical model for LC prediction
of SFC compression members. The confinement mechanics of steel tubes and FRP wraps are included in
the model, which was created using a database of 712 samples. The analytical model yields precise
predictions by considering the lateral confinement mechanism of SFC columns. For the LC of SFC
columns, statistical metrics of MAE = 427.23, MAPE = 283.65, R2 = 0.815, RMSE = 275.43, and a20
index = 0.73 are obtained by evaluation using the experimental database.
