摘要

En 中文
易损性函数是概率地震风险分析的三个关键组成部分之一，与其他组成部分（危害和后果及/或暴露模型）并列。原则上，易损性函数是针对特定结构的；然而，风险分析更常在较大（如区域）尺度上进行。在这种情况下，所谓的典型易损性曲线旨在应用于结构群体（即类别），而不是其特定成员。当这些曲线通过机械/数值方法获得时，它们通常基于数值模型，旨在代表所关注的类别。在本篇短讯中，讨论了一种在易损性函数推导中调和类别尺度和结构特定脆弱性的方法。它体现为一种层次模型，该模型在特定于结构的信息条件下退化为易损性函数，但可以在此类信息不确定时用于大规模风险评估。在推导元易损性函数时，讨论了响应面方法等选项。按照所提出的假设，此类建模方法还可用于从地震破坏观测中推导易损性函数。
