In order to provide guidelines to predict the wave impact and wave loading, it is necessary to systematically investigate the variations under different wave conditions, including non-breaking and broken waves. As a representative shape, the recurved parapet has gradually attracted more...

...-specific model from EU H2020 funded project COREWIND. Numerical simulations of wind-only, wave-only and wind-wave tests are conducted in OpenFAST. The SA results prove that among wind speed, significant wave height and peak wave period, wind speed is the most influential parameter and wave impact...

.... Such pressures may lead to high vibrations of some crucial structural elements (whipping). Slamming phenomena could be categorized in water entry problems, breaking wave impacts and green water loading. Water entry is a widely examined class of impact problems. Since the pioneering works of von Karman (1929...

... ABSTRACT In harsh sea state, offshore structures may suffer from extreme wave impact loads, which can result in seriously local structural damage. It is still a great challenge in predicting wave impact loads for offshore structures design, since extreme wave impact phenomenon is very complex...

.... During storm conditions, flood gates are often subjected to high water levels and wave loads. Impulsive wave impacts lead to vibrations of the structure, potentially amplifying internal stresses compared to the static situation. The problem of a flood gate vibrating in water is essentially a coupled one...
