历史建筑的易损性评估通常使用基于能力的方法进行，损失预测通过使用宏观地震烈度或峰值地面加速度的预期水平的正态或对数正态分布来获得。一些作者已经概述了这种方法的局限性。本文提出了一种基于现场观测破坏的地震易损性相关分析方法。该程序的各个方面都突出了应用到一个真实的情况。它示出了如何一旦在一个样本内的类型已被确定，他们每个人的脆弱性曲线可以推导出和预测累积损伤曲线的样本，直接调查的损坏数据是缺乏。最后，本文展示了如何使用失效机制方法来推导谱加速度和谱位移的损伤情况
Vulnerability assessment for historic buildings is usually carried out using capacity based approaches and prediction of losses is obtained by using normal or lognormal distributions for expected levels of macro seismic intensity or peak ground accelerations. Several authors have outlined the limitations of such approach. The paper presents a method to correlate analysis of seismic vulnerability using a failure mechanisms approach to observed in situ damage. The various aspects of the procedure are highlighted with application to a real case. It is shown how once the typologies within a sample have been identified, fragility curves for each of them can be derived and predictive cumulative damage curve obtained for samples for which direct survey of damage data is lacking. Finally the paper shows how the failure mechanism approach can be used to derive damage scenarios both in terms of spectral acceleration and spectral displacement
