The strength and ductility of core concrete are important factors influencing the bearing capacity of concrete-filled steel tube (CFST) structures, and an appropriate mixing amount of basalt fiber can change the toughness index of concrete. To examine the reinforcing effect of basalt fiber on the bearing capacity of long CFST columns, axial compression bearing capacity experiments were conducted on 15 long basalt fiber-reinforced concrete (BFRC)-filled steel tube columns and 9 long CFST columns to determine the ultimate bearing capacity, load-d...
