Abstract
Collision force exerted by single cuboid elements with different dimensions and sizes, subjected to dissimilar dam-break waves were investigated in this study to determine their ability to induce forces on a one storey residential structure with respect to the wave only forces. The observations indicated that a significant amount of additional force was exerted on the house model with several delivery modes and impacting patterns. The smaller size of cuboid subjected with lower wave conditions induced a considerably larger force, whereas for higher flow conditions, it was not as sensitive to the wave forces. In contrast, the larger size of the cuboid yielded a lower force for lower wave condition and displayed a considerable increment for larger waves. Several governing parameters were identified to be incorporated in the presently available formulations to estimate the debris impacts.
