Abstract
The dynamic response of concrete-filled fiber-reinforced polymer (FRP) steel tubes under impact loading was investigated in this study. Eleven column specimens with the same cross-sectional area but different lengths were tested on a drop-weight system. These specimens included eight concrete-filled carbon-FRP steel tubes, two concrete-filled glass-FRP steel tubes, and one concrete-filled steel tube as a baseline material. The time-history curves of impact force, acceleration, deflection, and strain were recorded. Experimental results showed that the improvement of FRP on the impact resistance of concrete-filled steel tubes is remarkable, especially for glass-FRP steel tubes.
