FE Modeling of a Historic Masonry Tower and Vibration-based Systematic Model Tuning

摘要

The paper presents and discusses the procedure developed for the calibration of the structural FE model of a Bell-Tower, within a wide investigation program aimed to support the preservation and restoration actions. Ambient vibrations induced by wind, micro-tremors and swinging of bells were recorded and the identified modal parameters, together with geometric and crack pattern survey were used to calibrate a 3D F.E. of the tower.
