Experimental and analytical investigation of the effect of external pressure on compressive behavior of concrete-filled steel tube stub columns

Nowadays concrete-filled steel tubes (CFTs) are used in many types of structures. In spite of significant advances, the application of this system has not widely adopted in marine structures. While due to the presence of hydrostatic pressure on the body of the tube, outward buckling, which may be considered as one of the weaknesses of the system, could be delayed. Therefore, theoretical and experimental studies were performed to investigate the...
