Numerous studies have delved into anticipating the loadcarrying capacity (LC) of fiber-reinforced polymer (FRP)-confined concrete-filled steel tubes (CFST) compression members (SFC) using limited and noisy data. However, none have undertaken a comparative assessment of the accuracy among various modeling techniques based on an extensive and refined database. This study aims to introduce an analytical model for forecasting the LC of SFC compression members. The model is developed utilizing a database comprising 712 samples, considering the mechanism of confinement of both tubes of steel and FRP wraps. By incorporating the lateral confinement mechanism of SFC columns, the analytical model yields precise predictions. As per the experimental database, the analytical model demonstrates statistics such as MAE = 427, MAPE = 283, R2 = 0.815, RMSE = 275, and an a20-index = 0.73, indicating its effectiveness in providing accurate predictions.
