This paper presents an experimental study on the impact behavior of steel cell dam supported by truss frame. The repeated impact load with incremental collision velocity is applied to the steel cell dam supported by truss steel frame by using the horizontal weight collision test apparatus. The impact load and the dent deformation were examined for the various filled material conditions. The axial force in the diagonal member of the truss frame which supports the steel cell was also measured as the representative transmitted force of the steel cell dam. The impact force at the collision point was remarkably reduced by installing the steel cell filled with sand or gravel. Therefore, the axial force of the truss frame which supports the steel cell became significantly smaller than the impact force at the collision point.
