Despite significant research advances on the seismic response analysis, there is still an urgent need for validation of numerical simulation methods for prediction of earthquake response and damage. In this respect, seismic monitoring networks and proper modelling can further support validation studies, allowing more realistic simulations of what earthquakes can produce. This paper discusses the seismic response of the “Pietro Capuzi” school in Visso, a village located in the Marche region (Italy) that was severely damaged by the 2016–2017 Central Italy earthquake sequence. The school was a two-story masonry structure founded on simple enlargements of its load-bearing walls, partially embedded in the alluvial loose soils of the Nera river. The structure was monitored as a strategic building by the Italian Seismic Observatory of Structures (OSS), which provided acceleration records under both ambient noise and the three mainshocks of the seismic sequence. The evolution of the damage pattern following each one of the three mainshocks was provided by on-site survey integrated by OSS data. Data on the dynamic soil properties was available from the seismic microzonation study of the Visso village and proved useful in the development of a reliable geotechnical model of the subsoil. The equivalent frame (EF) approach was adopted to simulate the nonlinear response of the school building through both fixed-base and compliant-base models, to assess the likely influence of soil–structure interaction on the building performance. The ambient noise records allowed for an accurate calibration of the soil–structure model. The seismic response of the masonry building to the whole sequence of the three mainshocks was then simulated by nonlinear time history analyses by using the horizontal accelerations recorded at the underground floor as input motions. Numerical results are validated against the evidence on structural response in terms of both incremental damage and global shear force–displacement relationships. The comparisons are satisfactory, corroborating the reliability of the compliant-base approach as applied to the EF model and its computational efficiency to simulate the soil–foundation–structure interaction in the case of masonry buildings.

尽管在地震响应分析方面取得了重大研究进展，但仍迫切需要验证用于预测地震响应和破坏的数值模拟方法。在这方面，地震监测网络和适当的建模可以进一步支持验证研究，从而可以更真实地模拟地震的产生。本文讨论了维索（Visso）的“ Pietro Capuzi”学校的地震反应，该学校位于意大利马尔凯地区的一个村庄，该村庄受到2016-2017年意大利中部地震序列的严重破坏。该学校是一幢两层的砖石建筑，其基础是承重墙的简单扩大，部分嵌入了内拉河的冲积松散土壤中。意大利结构地震台（OSS）将结构作为战略建筑物进行了监控，它提供了在环境噪声和地震序列的三个主震下的加速度记录。由OSS数据整合的现场调查提供了三种主震中每一种的破坏模式的演变。关于土壤动态特性的数据可以从维索村的地震微区划研究中获得，并被证明对开发可靠的地下土力工程模型很有用。采用了等效框架（EF）方法，通过固定基准模型和顺应基准模型来模拟学校建筑物的非线性响应，以评估土-结构相互作用对建筑物性能的可能影响。环境噪声记录允许对土壤结构模型进行精确校准。然后，通过使用在地下层记录的水平加速度作为输入运动，通过非线性时程分析来模拟砌体建筑对三个主震整个序列的地震响应。相对于结构响应的证据，无论是增量破坏还是整体剪切力位移关系，数值结果均得到验证。这些比较是令人满意的，证实了顺应性方法在EF模型中的可靠性及其在模拟砖石建筑情况下模拟土壤-基础-结构相互作用的计算效率。相对于结构响应的证据，无论是增量破坏还是整体剪切力位移关系，数值结果均得到验证。这些比较是令人满意的，证实了顺应性方法在EF模型中的可靠性及其在模拟砖石建筑情况下模拟土壤-基础-结构相互作用的计算效率。相对于结构响应的证据，无论是增量破坏还是整体剪切力位移关系，数值结果均得到验证。这些比较是令人满意的，证实了顺应性方法在EF模型中的可靠性及其在模拟砖石建筑情况下模拟土壤-基础-结构相互作用的计算效率。
