For the fact that there is a huge potential destructive danger of explosion impact on structure components
the dynamic response of concrete filled steel tubes(CFST) subjected to blast load were studied.The tests were conducted to the CFST with the same diameter and different wall thickness.The explosions of different dosages were tested and the pressure-time curve of blast wave
the strain curves in the bottom of component and the final deflection of component were measured.The relation of explosive force
casing hoop steel coefficient and component deformation was analyzed.The results showed that CFST had good ductility and impact resistance
improving the casing hoop steel coefficient of CFST structures can enhance the ability of anti-explosion.
