桥梁易损性曲线表示桥梁在给定地震动参数下达到一定损伤状态的概率，在交通网络整体地震风险评估中起着重要作用。目前用于生成桥梁易损性曲线的分析方法不能充分考虑所有主要的桥梁构件。研究表明，对于某些桥梁类型，忽略所有这些组件可能会导致对桥梁整体易损性的错误陈述。
Bridge fragility curves, which express the probability of a bridge reaching a certain damage state for a given ground motion parameter, play an important role in the overall seismic risk assessment of a transportation network. Current analytical methodologies for generating bridge fragility curves do not adequately account for all major contributing bridge components. Studies have shown that for some bridge types, neglecting to account for all of these components can lead to a misrepresentation of the bridges' overall fragilities.
