The knowledge on the distribution of energy with respect to the wave direction, which is commonly known as the directional , provides a better representation of the ocean's surface. A more realistic approach, considering the effect of the real sea's state would result in the optimum design of structures. The effect of wave screens on the reduction of pressures and forces on a vertical wall on its leeside due of directional waves has been investigated through physical model tests. This can be used by architects and engineers. For more details download the AutoCAD drawing file from our Cadbull website. Download this 2d AutoCAD drawing file.
