Wave Force on Buildings
A crown wall is a gravity based structure on top of a rubble mound breakwater which gains stability due to its own weight and friction between the base and contact surface of the rubble mound. Until now, these structures tend to be designed in a too conservative way, especially when the vertical distance between base slab and water level (base freeboard) increases. An experimental research was carried out in which the global stability of a crown wall was tested in which, amongst other things, freeboard was varied. It was concluded that current design methods overpredict vertical loads for increasing freeboard.
