“…Finally, exposure refers to the walled system itself as cultural heritage, as well as people, objects, buildings, roads or any element that can be potentially damaged by the failure of the town walls. Six risk classes have been considered, ranging from R0 to R5 [5]: R0 is assigned to units that are not exposed to any hazard; R1 and R2 are associated with acceptable levels of risk requiring on-site inspections; R3 is at the limit of acceptability and therefore requires regular monitoring actions; R4 and R5 are associated to unacceptable and critically unacceptable levels, respectively. Each element is subdivided into a number of units on which the evaluation is performed by means of several GIS-based forms.…”

“…These aspects affect the correctness of risk analysis that requires a critical judgment founded on a reading and interpretation of the object to be preserved and the phenomena to which it is subjected. In the architectural heritage domain, simplified multi-hazard approaches represent a significant step forward in the prioritisation of risk reduction measures [3] [4] [5]. Moreover, qualitative index-based methodologies can identify situations when detailed assessments are needed [6].…”

The problem raised by the steadily increasing number of failures in ancient town walls has recently attracted much interest. This typology of cultural heritage has always played a critical role in shaping local identities and still holds great potential as a cultural resource but poses substantial challenges in management terms. In fact, multi-disciplinary methodologies for their study and analysis are missing. The MO.M.U. project aims to safeguard ancient town walls in Tuscany (Italy) by introducing an integrated framework for their knowledge, diagnostic, assessment, monitoring and management. The proposed approach employs innovative non-invasive technologies and introduces a multi-hazard risk prioritisation methodology to address preventive conservation and programme interventions.

“…procedure to important UNESCO (United Nations Educational, Scientific and Cultural Organization) sites, thus highlighting its feasibility in the vulnerability assessment of large CH building portfolio. Moratti et al (2019) proposed a multi-level approach for the seismic assessment of URM churches based on five levels of data collection which lead to three levels of analysis refinement. At each level, performance indices are calculated as ratio of the structural capacity and the seismic demand, both expressed in terms of displacement.…”

“…However, performing detailed structural analyses for a large number of structures is cost-ineffective because it would require high-performance computing and specific technical resources. Therefore, simplified methods for multi-hazard risk prioritization/assessment of building portfolios (e.g., FEMA P-154, 2015), framed in multi-level frameworks (e.g., Moratti et al, 2019), represent essential tools to prioritize further detailed analyses and any DRR and/or resilience-enhancing intervention. Such simplified methods should allow an analyst to also account for the intangible value of CH assets and to consider their specific construction features by just using a small amount of information -to be typically collected in highly-complex urban settings, such as in developing countries.…”

Abstract. Multi-hazard risk assessment of building portfolios is of primary importance in natural-hazard-prone areas, particularly for the prioritization of disaster risk reduction and resilience-enhancing strategies. In this context, cultural heritage assets require special consideration because of their high vulnerability to natural hazards – due to ageing and the type of constructions – and their strong links with communities from both an economic and a historical/sociocultural perspective. As part of the Cultural Heritage Resilience & Sustainability to multiple Hazards (CHeRiSH) project, funded by the UK Newton Fund, this paper introduces a multi-hazard risk prioritisation framework specifically developed for cultural heritage assets. The proposed framework relies on a multi-level rapid-visual-survey (RVS) form for the multi-hazard data collection and risk prioritization of case-study assets. Because of the multi-level architecture of the proposed RVS form, based on three levels of refinement/information, an increasing degree of accuracy can be achieved in the estimation of structural vulnerability and, ultimately structural risk of the considered assets. At the lowest level of refinement, the collected data are used for the computation of seismic and wind risk prioritization indices, specifically calibrated in this study for cultural heritage assets with various structural/non-structural features. The resulting indices are then combined into a unique multi-hazard risk prioritization index in which the intangible value of cultural heritage assets is also considered. This is achieved by defining a score expressing the cultural significance of the asset. The analytic hierarchy process is extensively used throughout the study to reduce the subjectivity involved in the framework, thus obtaining a simplified, yet robust, approach which can be adapted to different building typologies. The proposed framework is applied to 25 heritage buildings in Iloilo City, Philippines, for which innovative, non-invasive techniques and tools for improved surveying have also been tested. Thermal and omnidirectional cameras have helped in the collection of structural data, together with drones for the inspection of roofs. Results of the study are presented and critically discussed, highlighting advantages and drawbacks of the use of new technologies in this field.

“…The analysis results of the model showed moderate agreement with the visual inspection performed in the site, which validated the model, and finally, the limit analysis using macro block analysis was also carried out to validate the main local collapse mechanisms of the church. Recently, there are many papers focused on the failure mechanisms of old masonry churches around the world, using different numerical modeling approaches, while other researchers studied the retrofitting possibilities using different approaches [16][17][18][19][20][21][22][23][24][25].…”
