Abstract. 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.
Keywords: Seismic Risk and Vulnerability; Structural Safety; Protection of

Multi-level assessment procedures of the seismic risk and
vulnerability of the built environment (residential buildings,
strategic and sensitive structures, infrastructures, cultural
heritage) for the sustainable reuse of existing structures
"While every year 50,000 acres of land is lost in new development, thousands of ancient villages and
historic towns risk the abandonment and the complete degradation. [...]." [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]
