A brick arch was loaded under laboratory conditions in three successive loading steps. No cracks were observed but reduction of natural frequencies and stiffness of the arch was experimentally documented. The stiffness was evaluated in a non-destructive test using an impact hammer and only two accelerometers. The proposed identification technique based on known experimental modal analysis theory is tailored to stiffness evaluation of masonry vaults. The results and the applied method are extensively discussed.
