The static and seismic retrofitting design, for masonry historical buildings, has to follow a right hierarchy of interventions, taking into account that to improve the seismic behavior of a masonry structure, it is necessary to guarantee a “closed box” behavior for the whole structural body or, in case of complex buildings, to guarantee a closed box behavior for each building's wing. Thus it is fundamental to distinguish the interventions for the global behavior improvement from those related to local reinforcements. In this chapter is then proposed a scheme of interventions hierarchy and, therefore, a related design process road-map together with the explanation of a correct design philosophy for the static and seismic retrofitting of historical masonry buildings. Moreover it is also reported an example of two distinguished levels of intervention, with numerical analyses supporting that solution.

Abstract Historical masonry structures that make up the cultural assets of a country constitute the identity of the society to which it belongs. For this reason, it should be protected and should be transferred from generation to generation. Earthquakes are threatening action to masonry structures. The force generated by the ground movement may cause shear cracks in masonry structures that may lead to fragmentation and even collapse of the structure. It is necessary to know the earthquake behaviour of masonry structures to be able to apply appropriate temporary shoring system after a damage caused by earthquake in order to prevent the future damages during aftershocks. Thus, the progress of the damages in the building is prevented and it is ensured to survive until detailed investigation or restoration. However, when the applied temporary shoring system designs were examined, the environmental conditions of the building were not taken into account in any guideline on immediate shoring. In this paper, temporary shoring system for 3 traditional houses of Bey District is designed for possible earthquake damages. This district has many registered civil architectures lined side by side along very narrow streets. Some masonry buildings were changed to reinforced concrete with multiple floors. This study includes the registration status of the buildings, their location, the number of floors to be supported, the heights between floors, the height of the forces that can be brought by the adjacent building elements, the width of the street where the facade to be supported, whether there is a window or door opening in the facade to be supported etc. If there are window or door openings, the distances of the opening to the corner points of the building and the distances between the two openings has to be recorded. According to these determinations, possible damages that may occur in the buildings are defined and a temporary shoring system is designed in accordance with the buildings and the surrounding conditions.

A Current

The assessment of the seismic safety level of masonry buildings is a current and important issue at the basis of the complex process of preservation of historical masonry buildings which constitute mostly the Italian and European towns. Nowadays, different approaches able to provide important information concerning the seismic safety level of masonry structures are available. Among these, fragility curves allow to have a prediction of potential damages during an earthquake of geographical areas characterized by similar construction typologies. The present paper concerns the derivation of fragility curves of masonry buildings, typical of Italian historical towns and mainly characterized by the possible occurrence of local out-of-plane collapse mechanisms. To this end, a real case is accounted in the study in order to consider specific parameters characterizing the constructions composing these territorial realities.
