The group is involved in the development of multi-level assessment procedures of the seismic risk and vulnerability of the built environment (residential buildings, strategic and sensitive structures and infrastructures, cultural heritage). In particular, these track is strongly addressed to the possibility of providing an effective supporting tool for the seismic safety assessment of historical masonry buildings and the design of interventions aimed at the rehabilitation and sustainable re-use of historical centres. Another class of structures that has been investigated is that of bridges and viaducts. The objective is to propose a simple mechanical vulnerability model, which can be easily applied at the regional scale. The model can be enriched in order incorporate the interaction with other hazards (such as floods,…) and a multi-objective “condition”/“functionality” rating, to be used in the evaluation and optimization of the intervention strategy.

[...]." [1]. The sustainability of settlement models is a priority, particularly in Italy, lacking in building land, where urbanization disorderly builds free land, floods agricultural areas, besieges the natural landscape resources, even occupying areas unsuited to settlement, as the ones at landslide risk. The expectations for the future foresee further pressure on urban centers, with an enlargement of the problem. In the past, a number of attempts, aimed Page 1 of 4 at promoting the restoration of abandoned or degraded historical centres, degraded industrial areas and cities' quarters, dismissed infrastructures were developed, but often resulted to be poorly incisive and enduring. Above all, they did not mark a turning point towards a new vision of the urban development, which has continued to promote brand new settlements. Nowadays, the option of reusing existing buildings is raising the attention of the building enterprises, but is inhibited by a number of technical and operational difficulties, mainly driven by the strict requirements of the recently issued technical seismic standards and by the complexity of the matter. The seismic building code [2], in fact, has been completely reviewed in the last 5 years, in order to comply with the most advanced international standards, and is particularly demanding with respect to the seismic safety assessment of existing constructions. This generated confusion among professionals and technicians, as pointed out by the significant efforts put in place by the scientific community and by professional associations to support and update the technicians and did not favour a recovery of the construction market. Due to their strategic and central position in the city, to the high potential for settlement and to the historical, cultural and touristic value, the importance of focusing on reuse of historic centres and neighbourhoods is now recognized at all levels, and is the subject of great interest by different stakeholders. In this context, a crucial point is the seismic and structural safety of buildings. This is a very complex problem which interferes with every step of the strategies of sustainable reuse of existing buildings, and is one of the central object of the research activity of the group. Within this framework, the group has been involved, in the last few years, in the development of Multi-level assessment procedures of the seismic risk and vulnerability of the built environment (residential buildings, strategic and sensitive structures and infrastructures, cultural heritage). The analyses start from the regional scale, in order to provide a rational basis for the prioritization of interventions, mitigation strategies and fund allocation. In particular, these track is strongly addressed to the possibility of providing an effective supporting tool for the seismic safety assessment of historical masonry buildings and the design of interventions aimed at the rehabilitation and sustainable reuse of historical centres. Another class of structures that has been investigated in detail is that of bridges and viaducts. The objective is to propose a mechanically based –but simple – vulnerability model that can be easily applied at the regional scale. Besides the seismic vulnerability, the model is being enriched in order to account for the interaction with other hazards (such as floods, undermining, …) and incorporate a multi-objective definition of the “condition” and “functionality” rating, to be used in the evaluation and optimization of the intervention strategy. With regard to these issues, the research group has developed several studies and research projects in collaboration with local authorities and administrations. For example, the regional municipality of Puglia has promoted studies on the vulnerability of Apulia, with reference to residential buildings, school buildings and bridges (Antaeus Project, Project Sprepas). The results of the research studies have been published in several papers and books [3-32] References [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] “The new life of old villages”, Tekneco (2012), n.6 2012, www.Tekneco.it.
