This paper presents an impact analysis of steel cell dam supported by truss frame. In advance to this study, a collision test with a model steel cell dam was carried out in order to investigate impact force on a steel cell and transmitted impact force on a truss frame. The axial force of the truss frame which supports the steel cell become significantly smaller than the impact force at the collision point. In order to evaluate this result from analytical point of view, the simulation analysis was performed by using finite element method to prove the validity of the transmitted impact force obtained from the collision test. Furthermore, how the stress wave propagates through the steel cell is discussed.
