Experimental study of CFDST columns infilled with UHPC under close-range blast loading

•CFDST columns can effectively withstand severe blast load without failure.•The failure mode was global flexural response with no signs of steel buckling.•The increase in explosive charge weight caused a larger mid-span deflection.•The applied axial compressive load led to a reduction in the peak de...
