Abstract
This work presents an account of the results of diagnostic analyses conducted by the authors on the portal of Palazzo dei Priori in Perugia, Italy. After summarizing the main events that may have affected the structural behavior of the portal in the course of time, this article describes the results of the finite element method (FEM) tests conducted on a three-dimensional model of the portal. The analysis of these results made it possible to investigate the origin of the surveyed crack pattern and to evaluate the seismic vulnerability of the portal also as regards its structural response to the seismic activity at the level expected for the Perugia area.
