This study focuses on quantifying the impact of implementing a recently proposed seismic classification procedure for acceleration-sensitive non-structural elements on the seismic economic losses of a three-storey case-study building in Italy. The seismic classification procedure for acceleration-sensitive non-structural elements is based on the performance observed during qualification shake table tests at predefined levels of seismic intensity according to the Italian seismic hazard map. A procedure based on updating the available component fragility functions of acceleration-sensitive non-structural elements is used to link the seismic classification procedure to seismic loss estimation of a case-study school building to quantify the effect of applying the seismic classification procedure for acceleration-sensitive non-structural elements in terms of losses. The case-study building is analysed for six different sites in Italy, considering four structural seismic retrofit strategies, and five levels of non-structural seismic classification. The results demonstrate that the expected annual loss for the building decreases as the seismic qualification performance (or class level) of the acceleration-sensitive non-structural elements increases. This study paves the way for more extensive studies that could help quantify the economic benefits of implementing the seismic classification procedure for non-structural elements at a regional level.

加速度敏感非结构元分类对意大利某案例研究建筑地震损耗估计的影响


本研究的重点是量化最近提出的加速度敏感非结构元件地震分类程序对意大利一栋三层案例研究建筑的地震经济损失的影响。加速度敏感的非结构构件的地震分类程序基于根据意大利地震危险地图，在预定义的地震烈度级别下进行定性振动台测试期间观察到的性能。使用基于更新加速度敏感非结构元件的可用组件脆性函数的程序将地震分类程序与案例研究学校建筑的地震损失估计联系起来，以量化对加速度敏感的非结构元件应用地震分类程序在损失方面的影响。案例研究建筑分析了意大利六个不同地点，考虑了四种结构抗震改造策略和五个级别的非结构性抗震分类。结果表明，随着加速度敏感非结构元件的抗震鉴定性能（或等级）的增加，建筑物的预期年损失会降低。这项研究为更广泛的研究铺平了道路，这些研究可能有助于量化在区域层面对非结构元素实施地震分类程序的经济效益。
