Article
The safeguard of historical heritage cannot disregard a rational assessment of the seismic vulnerability of the assets, especially in areas as Italy where high exposure and hazard may lead to significant risk. In this context, while established empirical methods based on observed damage after earthquakes are available for some constructional typolo...
Conference Paper
Historical masonry monuments, among which churches and religious buildings represent a conspicuous part in Europe, are prone to severe damage and even destruction in case of exceptional loadings as earthquakes. Seismic assessment and protection of such structures has thus become a high-priority goal as well as an exceptional challenge given the com...
Article
In this paper, an experimental investigation addressed at the characterization of compressive strength of a weak units-strong mortar masonry is presented. This masonry, made with natural units of calcarenite improperly named “tufo”, is massively recurrent in the historic center of Matera, an UNESCO site since 1993. The tufo masonry was used for bui...

Simulating the mechanical behavior of masonry structures with reasonable approximation using numerical models is a complex issue, mainly due to the uncertainties affecting the selection of mechanical parameters. Since destructive testing is in some cases impossible, the Italian building code provides ranges for the parameters based on masonry type...
Chapter
The protection and conservation of historical monumental assets is a priority for contemporary societies. As it is widely recognized, historical masonry buildings (and in particular masonry churches) are unable to adequately withstand horizontal actions and generally suffer heavy damage if struck by a seismic event. Although a correct evaluation of...
Chapter
A large portion of the Italian building heritage is made of masonry constructions, which were erected in the first decades of the last century and were conceived to support gravitational loads only. Many research activities have been carried out in order to propose retrofitting techniques aimed at improving seismic behaviour of existing masonry bui...
Chapter
Large part of the historical heritage is characterised by the presence of timber elements for floors and roof, which need to sustain vertical load and comply with safety prescriptions of current building codes. One of the main stages in the assessment of historical timber structures is the evaluation of material properties. This is not a trivial ta...
Chapter
Due to bridge collapses recently occurred, it is now very clear that the conservation and the preservation of existing infrastructures is a real priority. On the other hand, many of the existing bridges were built before the first half of the last century on the basis of outdated design criteria. Therefore, they are affected by a significant ancien...
Chapter
The application of damped bracing systems is seriously limited by the lack of a standardized design procedure. The traditional methods appropriate for conventional structures (such as the use of a behaviour factor) become worthless. On the other side, the nonlinear response history analysis is complex and computationally demanding and its implement...
