This paper describes the experiments carried out on a mediaeval masonry tower in the historic centre of Lucca and some finite element numerical simulations of the tower’s experimental response. The Guinigi Tower, one of the most iconic monuments in Lucca, has been continuously monitored by high-sensitivity seismic stations that recorded the structure’s response to the dynamic actions of the surrounding environment. The monitoring campaign results have been analysed to show the effectiveness of dynamic monitoring as a valuable source of information on the structural properties of the tower. The dynamic analyses of the tower and the surrounding palace subjected to some seismic events recorded during the experiments have highlighted the capabilities of experiment-based finite element modelling. The calibration of the finite element model and the numerical analysis have been carried out by resorting to procedures developed at ISTI-CNR and able to consider the nonlinear behaviour of masonry materials.

本文描述了在卢卡历史中心一座中世纪砖石塔上进行的实验以及塔实验响应的一些有限元数值模拟。吉尼吉塔是卢卡最具标志性的古迹之一，高灵敏度地震台一直对其进行持续监测，记录该结构对周围环境动态作用的响应。对监测活动结果进行了分析，以显示动态监测作为塔楼结构特性的宝贵信息来源的有效性。对塔楼和周围宫殿在实验期间记录的一些地震事件的动态分析突出了基于实验的有限元建模的能力。有限元模型的校准和数值分析是通过 ISTI-CNR 开发的程序进行的，并且能够考虑砌体材料的非线性行为。
