摘要

本文总结了曼图亚加比亚塔前15个月连续动态监测的结果。2012年5月意大利地震事件发生后，对塔楼进行了广泛的调查，建议在建筑的上部区域安装动态监测系统。连续记录的信号允许自动识别结构的关键振动模式的固有频率，并清楚地检测温度对固有频率的影响。频率与温度之间的相关性研究还揭示了远场地震所确定的不可逆结构效应，证明了基于频移的损伤检测技术的有效性。

Structural health monitoring of a historic masonry tower

The paper summarizes the results of the first 15 months of continuous dynamic monitoring of the Gabbia tower in Mantua. After the Italian seismic events of May 2012 a wide investigation program was performed on the tower, suggesting the installation of a dynamic monitoring system in the upper region of the building. The continuously recorded signals allowed the automated identification of the natural frequencies of the key vibration modes of the structure and the clear detection of the effects of temperature on the natural frequencies. The study of the correlation between frequencies and temperature also revealed the non-reversible structural effects determined by a far-field earthquake, proving the effectiveness of damage detection techniques based on frequency shifts.
