人口众多、经济发达的沿海大城市容易遭受飓风和风暴潮灾害的损失。虽然目前的设计规范考虑了强风和风暴潮的联合发生，但关于美国东海岸和墨西哥湾沿着飓风和风暴潮的现场特定联合分布的信息仍然稀少且有限。本文建立了南卡罗来纳州查尔斯顿市飓风和风暴潮联合概率分布。一个随机飓风模型被用来模拟5,000年的合成飓风。将模拟的飓风输入ADCIRC（高级环流）浪涌预测模型，以计算选定位置的浪涌高度。计算的峰值风速和涌浪高度被用来生成在每个位置的联合概率分布。开发的这些联合分布可用于多灾害设计或风险评估框架，以考虑飓风和风暴潮灾害的综合影响。
Major coastal cities, which have large populations and economies, are easily suffered from the losses due to hurricane wind and storm surge hazards. Although current design codes consider the joint occurrence of high wind and surge, information on site specific joint distributions of hurricane wind and storm surge along the U.S. Eastern Coast and Gulf of Mexico is still sparse and limited. In this paper, joint probability distributions of combined hurricane wind and storm surge for the City of Charleston, SC is developed. A stochastic hurricane model was used to simulate 5,000 years of synthetic hurricanes. The simulated hurricanes were inputted into the ADCIRC (Advanced Circulation) surge prediction model to compute the surge heights at selected locations. The calculated peak wind speeds and surge heights were employed to generate the joint probability distributions at each location. These joint distributions developed can be used in a multi-hazard design or risk assessment framework to consider the combined effects of hurricane wind and storm surge hazards.
