本文在地震危险性评估的易损性分析的背景下，对结构地震试验的试验结果进行了评估。提出了一种方法来评估为增加激励而测试的试件的脆弱性，以补偿同一试件中的损伤累积(而不是为每一级激励测试原始试件的非常昂贵的替代方案)。该方法提供了与“修正的”地震烈度有关的损伤演化，该烈度是由能量输入概念得出的。此外，本文还说明了在先验知识和实验证据相结合的基础上，使用贝叶斯推理策略来更新给定类型的脆弱性。
The paper presents a contribution for the assessment of experimental results obtained in seismic tests of structures in a context of fragility analysis for earthquake risk assessment. A methodology is proposed to estimate the vulnerability of specimens tested for increasing excitations, compensating for the damage accumulation in one same specimen (as opposed to the very expensive alternative of testing virgin specimens for each level of excitation). The method provides the damage evolution in relation to a “corrected” seismic intensity derived from the energy-input concept. Furthermore the paper illustrates the use of Bayesian inference strategies to update the fragility of a given typology on the basis of the combination of prior knowledge with experimental evidence.
