Structural interventions on historical masonry buildings: review of Eurocode 8 provisions in the light of the Italian experience

The paper presents a critical review of Annex C, section 5, of the Eurocode 8 Part 3, which focuses on the structural interventions for existing masonry buildings. The considerations herein drawn up are developed in the light of the Italian experience after recent earthquakes, and refer particularly to the Codes and Guidelines currently in force, which are also based on the results of extensive experimental researches carried out in Italy and Europe. The limits and the deficiencies of Eurocode 8 Part 3 (Annex C.5) are pointed out following the logical structure of the Italian norms, that are organized by defining the objectives and the performance requirements to be achieved through the strengthening interventions. Suggestions for reviews and improvements are given, considering the significance of this document and the need for general and shared rules to be applied, in the field of seismic strengthening of masonry buildings, at an European level.
