Abstract

The Cathedral of Modena, built at the end of the XI century, is one of the most important exam-ples of the Romanesque art in Italy. In 1997, the monument was declared as “UNESCO World Heritage” site. The first phase for a meaningful interpretation of the structural behaviour of such a complex monument is the static analysis, which first requires the study of the loads path to the ground. The objective of the present paper is to study the structural behaviour of the Mo-dena Cathedral through a multidisciplinary integrated approach, which makes use of the “sur-vey” as a tool able to provide a comprehensive knowledge of the building. The “survey” is here intended as the integration between: (i) the historical reconstruction of the main interven-tions and modifications of the structural system over the years; (ii) the materials characteriza-tion, (iii) the topographic survey of the geometry of the superstructure and the evolution of the settlements; (iv) materials state of degradation. The information as obtained from the “survey” are fundamental to understand the global structural behaviour of the building and how the dif-ferent portions of the buildings interact between each other. In this work, the reconstruction of the evolution of the structural configuration is analysed in order to identify the portions of the structure built in the same age as a unique structure, namely the “substructures” of the Cathe-dral. Each substructure is first analysed as an independent structure through simple limit sche-matizations in order to obtain the stress levels on the structural elements and correlate the re-sults with the state of damages as observed in situ. Then, finite element models of increasing complexity (2D models, 3D models with fixed base conditions, and 3D models accounting for the soil-structure interaction) are developed. The results of the static analyses as obtained from FE models are finally compared with the results of the simple static analyses performed on the substructures.
