This paper puts forward a steel strengthening method using mortar-filled FRP tubes. Through axial compression test on eighteen specimens of different cross section types, slenderness ratios and wrapping FRP fabrics layers, the failure mode, bearing and ductility capacity have been obtained. On the basis of statistics, the bearing capacity of confined specimens increased by 44%-243%, most of which exceeded whole cross-section yield load, and the deformation capacity at the peak load and ductility increased much. In general, the method is fast, convenient, economic and effective, and presents further potential research areas like light weight and green sustainable direction.
