A reliable and predictive model of an existing structure entails the use of model updating techniques, which are usually performed on the basis of operational modal analysis campaigns. In this paper, a new model calibration strategy is proposed that adopts a multiphysics approach to exploit data collected by both static and dynamic monitoring systems. More specifically, mechanical and temperature data are assimilated into the model through a thermoelastic updating. The proposed scheme is validated with numerical simulations and applied on the Sanctuary of Vicoforte, a complex historical building that is subjected to both static and dynamic monitoring.

热弹性有限元模型的更新及其在纪念性建筑中的应用

现有结构的可靠且可预测的模型需要使用模型更新技术，该技术通常是在运营模式分析活动的基础上进行的。在本文中，提出了一种新的模型校准策略，该策略采用多物理场方法来利用静态和动态监视系统收集的数据。更具体地说，通过热弹性更新将机械和温度数据吸收到模型中。所提出的方案通过数值模拟进行了验证，并应用于Vicoforte避难所，这是一幢受静态和动态监控的复杂历史建筑。
