Contribution to the knowledge of wide span wooden roofing in the area of Bologna

This study focuses on the analysis of wooden roofs in some of the most important churches of Bologna. An operational method has been set up to make the analysis repeatable and the results comparable in each different building. This paper presents the main steps of this methodology as well as the results of its application into two different case studies: St. Peter’s Cathedral and the church of San Salvatore Maggiore. The aim is to improve the proposal of restoration intervention on these construction systems.
