== Abstract ==

This paper investigates the capability of advanced numerical modelling techniques
to simulate experimental observations as damage or deformations in complex masonry
structures. The case of the church of St. Bassiano in Pizzighettone, Cremona Italy is chosen.
A multidisciplinary research was set up to collect data as geometric survey with Lidar
technology, measurement of axial force in the iron tie rods of the nave, and a monitoring system
for crack widths. The data was used as an input to develop and validate a finite element model
to study the structural damage and the evolution of the building in time.
The finite element model features a three-dimensional geometry, which is created in part
automatically, taking advantage of a parametric model for ribbed masonry vaults, proposed
recently by the authors. The FE model results in close adherence with the real building
structure, due to the accuracy of the collected data. The simulation model features a continuum
plastic damage model to take into consideration the masonry constitutive behaviour.
The results show how the system response is closely related to the structural evolution in
time, associated with the dismantling of the chapels on the south side and the addition of the
iron tie rods in the nave. The numerical simulations highlight also the important effect of the
soil settlements in the present crack pattern. The information obtained using this approach will
allow to understand the active mechanisms in the building and to optimise the technical
interventions in critical parts of the structure.
