Abstract:In the past few decades, climate change has been leading to more severe hurricanes. Hurricanes have been identified as the starting point of weather-related disasters in coastal regions due to their coincident generation of extreme winds, high storm surge, strong waves, and heavy rainfall. Bridges in coastal regions are exposed to these multi-hazards. To mitigate these threats, to increase the resilience of bridges, and to take pro-active adaptation measures, the overarching goal of this research project is to apply multi-phase direct numerical simulation to understand the wind-surge-wave interaction, which will be used to better quantify the combined loading on bridges from multiple hazards. The obtained results can be used to inform the improvement of the AASHTO Bridge Design Specifications to accommodate the future climate change, enhancing the resilience of bridges.
