Abstract:

Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural response to wave loading is poorly understood. In this study, a simple model is presented to estimate impact loads due to wave slamming on the concrete armor unit, dolos. A nonlinear dynamic analysis indicates that the units will experience a structural failure at hydrodynamically stable wave conditions.
