To investigate the ultimate behavior of high-strength concrete filled steel tube (CFT), dynamic loading test of CFT beam-columns has been carried out. The test results exhibit that the maximum strength of every specimen is larger enough than the ultimate strength predicted by the generalized superposed strength method but the ratio of them changes according to the relation between the strength of steel tube and filled concrete. It is also shown that there are two kinds of ultimate state which are the crack development in steel tube and the excessive accumulation of plastic axial deformation and special attention should be paid to the former ultimate state because it is brittle fracture in the case that CFT is filled with high-strength concrete and subjected to dynamic load.
