Understanding the behavior of historic structures that have undergone structural changes, restorations, and damage over time is still a significant challenge for structural engineers, particularly in those countries subject to high seismic risk, such as Italy. The study of built heritage for its prevention and conservation is an active research topic, due to the numerous uncertainties present in historic structures. Finite element modelling has become the most common and accessible method to study the behavior of complex masonry structures, however, the gap between numerical and experimental analysis may lead to erroneous results. Model updating techniques can reduce the discrepancy between the behavior of the numerical models and the testing results. The goal of this work is to illustrate a methodology to integrate the information derived from local, global, and geotechnical investigations into the finite element model of the masonry historical church of San Giovanni in Macerata, considering the Douglas–Reid model updating method. The PRiSMa laboratory of Roma Tre University carried out local investigations such as sonic tomography, video endoscopy and double flat jack tests, along with five ambient vibration tests that were processed through the operational modal analysis to extrapolate the dynamic properties of the building (modal frequency, modal shape vector and modal damping). The combined use of global, local and geotechnical information implemented in the methodology effectively reduced the uncertainties of the model and led the refinement and validation of the most relevant structural parameters.

对于结构工程师，尤其是在那些遭受高地震风险的国家（例如意大利），了解随着时间的推移经历过结构变化，修复和破坏的历史建筑的行为仍然是一项重大挑战。由于历史建筑中存在许多不确定性，因此对建筑遗产的保护和保护进行研究是一个活跃的研究课题。有限元建模已成为研究复杂砌体结构行为的最常用和可访问的方法，但是，数值分析与实验分析之间的差距可能会导致错误的结果。模型更新技术可以减少数值模型的行为与测试结果之间的差异。这项工作的目的是说明一种方法，该方法将考虑到道格拉斯-里德（Douglas-Reid）模型更新方法的，将从本地，全球和岩土工程研究中获得的信息整合到Macerata的San Giovanni砌体历史教堂的有限元模型中。罗马特雷大学（Roma Tre University）的PRiSMa实验室进行了局部调查，例如声波断层扫描，视频内窥镜检查和双扁形千斤顶试验，以及五种环境振动试验，这些振动试验通过运行模态分析进行处理，以推断建筑物的动态特性（模态频率，模态矢量和模态阻尼）。结合使用全局，
