Analisi di torri in muratura in presenza di distacco dei paramenti

An accurate diagnostic investigation was carried out by the Authors on the Isso Tower in the city of Castelleone. The tower, around 50m high, was built between the 11th and the 12th and underwent heavy interventions toward the middle of the past century, when a reinforced concrete tank for the city water supply was built internally. The load-bearing walls are built in solid bricks, but, according to a technique used in the medieval times, they were covered on the internal and external faces by a cladding one brick thick, which had the function of hiding the rough internal masonry. The most serious source of problems concerning the safety of the structure is represented by the detachment of large portions of this cladding. Part of the investigation had precisely the aim of quantifying, through maps of the detachments, the entity of the damages and of calculating, by a FE model, the effects of the detachments in terms of stresses. This preliminary study is the base for the necessary conservation works that the municipality intends to carry out in order to open the tower to the tourists.
