Numerical Study on Tsunami Force on Coastal Bridge Decks with Superelevation

Journal of Marine Science and Engineering, 2023
Many coastal bridges have been destroyed or damaged by tsunami waves. Some studies have been conducted to investigate wave impact on bridge decks, but there is little concerning the effect of bridge superelevation. A three-dimensional (3D) dam break wave

3D Numerical Modeling and Quantification of Oblique Wave Forces on Coastal Bridge Superstructures

Journal of Marine Science and Engineering, 2022
Simply supported bridges comprise the majority of bridge systems in coastal communities and are susceptible to severe damage from extreme waves induced by storms or tsunamis. However, the effects of oblique wave impacts have been less investigated due to

Study of the Interaction between Regular Waves and a Wind-Fish Combined Structure

Applied Sciences, 2023
The combination of a wind turbine and fish cage (wind-fish) is able to solve the complex issue of power supply for deep-sea aquaculture. Nevertheless, the hydrodynamic coupling between the fish cage and the wind turbine foundation is increasingly complex,
