<p>The sequence of major earthquakes that has affected Italy in recent decades has required the use of materials and innovative techniques for the security of damaged buildings. Fibre Reinforced Polymer (FRP) represents a novelty in the field of seismic improvement techniques applicable also to historical masonry buildings. The use of composite materials can respect the conservation principles of the monumental buildings. This study describes the effectiveness of the seismic improvement techniques carried out by means of FRP in the Spoleto cathedral (Italy) after the 1997 Umbria-Marche earthquake. The strengthening work concerned the making safe of damaged vault structures by means of gluing fibreglass bands (GFRP). After 20 years, during the 2016 Amatrice-Norcia earthquake, near Spoleto, the cathedral reinforced with the GFRP bands has not suffered any damage demonstrating the effectiveness of the seismic strengthening techniques.</p>

Masonry buildings are ordinarily complex construction systems and there is a lack of knowledge and information concerning the behavior of their seismic response. Due to the life safety of masonry buildings under seismic effects are very essential, numerical modeling and analysis of the buildings are an important issue. Because of the insufficient seismic resistance on structural members such as jack arch slabs and masonry walls, numerical studies have become necessary to determine the level of the structural strength of the structures. The tensile strength of load-bearing walls in the buildings is lower whereas, the compressive strength is higher. In this way, tensile cracks occur at structural members due to insufficient tensile resistance. Therefore, the tensile stress locations in the structure are critical. The study focuses on the assessment of historical masonry buildings from the point of seismic resistance. The entire process is performed using a case study from a historical masonry building. In this study conducted in this respect, the existing situation of a historical building using numerical analyses were presented with the cross-disciplinary study of civil engineering and architecture. The linear elastic analysis is selected as an analysis method. The seismic parameters are determined based on the Turkish Earthquake Code (TBEC 2018). Consequently, the study is performed to determine the seismic-resistant of historical buildings within the scope of numerical analyses.

Historic masonry buildings experience a high seismic vulnerability: innovative intervention strategies for strengthening, based on the use of fibre-based composite materials are gradually spreading. In particular, the coupling of fibre-based materials with mortar layers (Fibre Reinforced Mortar technique - FRM) evidenced a good chemical and mechanical compatibility with the historical masonry and proved to be effective for the enhancement of both in-plane and out-of-plane performances of masonry, contrasting the opening of cracks and improving both resistance and ductility. The resistant mechanisms that arise in FRM strengthened masonry walls subjected to in-plane horizontal actions are analyzed in the paper and a practical design approach to evaluate their performances is illustrated, evidencing the dominant collapse mode at the varying of the masonry characteristics. Some masonry walls are analyzed numerically and analytically, as “case study”.
