In the Middle Ages, Pavia was characterized by the presence of several masonry towers; some of them are still existing in the historic center, while many others failed or were demolished in the past centuries. Since 1989, when the collapse of the Civic Tower occurred, the municipality of Pavia started a huge program of analysis and verifications for all the survived towers, in order to evaluate their residual resistance and to prevent further collapses. Structural evidences required some consolidation interventions for three towers (San Dalmazio, Maino and Fraccaro). In this memory two similar interventions realized by the author on the tower of San Dalmazio and Maino are presented. The consolidation solution is called "tower in tower", and consists in the insertion of a steel truss tower inside the masonry one, connected to the perimeter walls through more than 300 steel stays. Such elements are able to transfer part of the self weight of the masonry to the inner steel truss, reducing the compressive stresses at the base.

Abstract
In the Middle Ages, Pavia was characterized by the presence of several masonry towers; some of them are still existing in the historic center, while many others failed or were demolished in the past centuries. Since 1989, when the collapse of the Civic Tower occurred, the municipality of Pavia started a huge program of analysis and verifications for all the survived towers, in order to evaluate their residual resistance and to prevent further collapses. Structural evidences required some consolidation interventions for three towers (San Dalmazio, Maino and Fraccaro). In this memory two similar interventions realized by the author on the tower of San Dalmazio and Maino are presented. The consolidation solution is called "tower in tower", and consists in the insertion of a steel truss tower inside the masonry one, connected to the perimeter walls through more than 300 steel stays. Such elements are able to transfer part of the self weight of the masonry to the inner steel truss, reducing the compressive stresses at the base.File | Dimensione | Formato | |
