In this study, impact loading tests of six specimens were conducted using the falling weight impact loading machine in order to get the basic knowledge on the response characteristics of concrete-filled steel tubular (CFT) specimens. Although the maximum velocity of Tsunami might be estimated as 15m/s in typical seashore, it may be thought that around 7m/second is the maximum velocity of the flotsam in inland. The impact velocity of falling weight is proportional to the square root of the falling height of the weight, so that the maximum falling height in this test is determined as 2.5m corresponding to the velocity of 7m/s. Another four specimens were also conducted under static condition which are the standard references to be compared with the specimens subjected to impact loads. The specimens are simply-supported beams, and the impact loads or static loads concentrically and vertically applies to the mid-span of the beams. The test specimens are circular and square CFT specimens and circular and square vacant steel tubular specimens. The increase of heaviness and velocity of the weight increase the plastic energy dissipation and the input energy for specimens. As the result of impact loading test, the CFT specimens could sustain much higher levels of the heaviness and velocity of falling weight than those of vacant steel tubular specimens.
