The vault of the hall at the first floor of Palazzo Franchetti in Pisa is a masonry barrel-vaulted with pavillion heads.
It has a very wide extent, with an area of over 118 mq and a longitudinal extension and maximum transverse respectively of 14.17m and 8.80m; in the transverse direction the vault shows a section with very pronounced curvature, while in the longitudinal direction it is almost horizontal. The height from the floor of the hall is over 8,20m. The frescoes intrados representing the Olympus of the Gods, was created by painter Agostino Ghirlanda.
The NOSA-ITACA code has been used to understand the origin of the crack pattern present at the intraods of the vault and to estimate the bearing capacity of the same.
