This paper presents an experimental approach on the dynamic load-carrying capacity of the steel pipe beam with a flange joint. First, the current status of steel pipe beams with joints is presented. Second, the static and dynamic (rapid-speed) load tests are performed for the steel pipe cantilever beams with a flange joint by changing the loading position. The test results showed that the failure mechanism of flange joint by dynamic load was remarkably damaged rather than the one by static load at the loading position near the flange joint. This cause may be due to the effect of repeated loads and strong shearing force. On the other hand, the damage at the loading position far from the flange joint was only flexural-tension and no difference between static and dynamic loads.
