The present study deals with the definition of a numerical model able to describe the actual dynamic behaviour of an historical slender structure: the bell tower of Santa Maria di Loreto Church in Mola di Bari (Bari, Italy). Thus, a dynamic experimental campaign has been performed during which the oscillations due to environmental actions have been recorded. Subsequently, such data have been elaborated by means of operational modal analysis methods operating both in the frequency and in the time domain. The identified modal properties have been utilised to update a finite element model of the bell tower in order to match the experimental results. A nonlinear static analysis has been performed on the validated finite element model with the aim of evaluate the structural behaviour under seismic actions.

Abstract

The present study deals with the definition of a numerical model able to describe the actual dynamic behaviour of an historical slender structure: the bell tower of Santa Maria di Loreto Church in Mola di Bari (Bari, Italy). Thus, a dynamic experimental campaign has been performed during which the oscillations due to environmental actions have been recorded. Subsequently, such data have been elaborated by means of operational modal analysis methods operating both in the frequency and in the time domain. The identified modal properties have been utilised to update a finite element model of the bell tower in order to match the experimental results. A nonlinear static analysis has been performed on the validated finite element model with the aim of evaluate the structural behaviour under seismic actions.
