METHODOLOGY FOR THE ANALYSIS OF COMPLEX HISTORICAL WOODEN STRUCTURES

This paper deals with several items concerning the restoration of historical wooden structures. Firstly general problems related to the identification of the material and of the whole structural complex are faced. They are mainly influenced by either wood defects and degradations or past technologies for construction. An overview of the possible upgrading intervention is also introduced. Therefore the paper has been focused on a study case of historical roofing structure. In particular the detailed geometrical and mechanical surveys are presented. The main aspects of the structural modeling are evidenced and the results of the structural analysis are discussed. On the bases of the structural behavior pointed out, the appropriate retrofitting intervention has been illustrated.
