飓风是影响世界各地社区的最昂贵的自然灾害之一。飓风的登陆涉及不同的危险源（即，风、风载碎片、洪水和雨水），这些因素相互作用，产生给定结构的危险情景。因此，可以将飓风视为多种灾害情景，必须将其作为多种灾害情景进行分析。在这一章中，概率性能为基础的飓风工程（PBHE）框架是用于风险评估的住宅结构遭受飓风灾害。通用多层蒙特卡罗模拟（MCS）方法专门用于预制或非工程建筑物的风险评估。一个假设的住宅受到风，风载碎片，洪水和降雨的综合危害的案例研究被认为是说明概率风险评估的顺序过程。从应用实例中得到的结果包括维修费用的目标住宅建筑，由于每一个危险和他们的综合影响的年可收回的概率。这些结果突出了考虑不同危险源之间相互作用的重要性。
Hurricanes are among the most costly natural hazards affecting communities worldwide. The landfall of a hurricane involves different hazard sources (i.e., wind, wind-borne debris, flood, and rain) that interact to generate the hazard scenario for a given structure. Thus, hurricanes can be viewed and must be analyzed as multi-hazard scenarios. In this chapter, a probabilistic Performance-Based Hurricane Engineering (PBHE) framework is used for the risk assessment of a residential structure subjected to hurricane hazard. The general multilayer Monte Carlo simulation (MCS) approach is specialized for the risk assessment of pre-engineered or non-engineered buildings. A case study of a hypothetical residential house subjected to the combined hazards of wind, wind-borne debris, flood, and rainfall is considered to illustrate the sequential procedure for the probabilistic risk assessment. The results obtained from the application example include the annual probability of exceedance of repair cost for the target residential building due to each hazard and their combined effects. These results highlight the importance of considering the interaction between different hazard sources.
