“…The continued use of essential facilities is crucial for the functionality of urban systems. However, recent studies have highlighted the high seismic risk of these constructions and network particularly in megacities [1][2][3][4]. The need to enhance their seismic capacity with suitable retrofitting interventions has been highlighted.…”

“…They solve complex problems in a technically valid and practically convenient way improving the transparency, the analytic rigor, auditability, and conflict resolution of decision makers [8]. Some interesting applications have been carried out to provide prioritization strategies for the seismic risk mitigation of essential facilities [1,4], and to select the optimal rehabilitation system in a single building [9,10].…”

“…The Analytic Hierarchy Process (AHP) method [12,13] can be applied to assess quantitative the qualitative judgement criteria and determine criteria weights, while the TOPSIS method [14] can be used to compare and choose the optimal retrofit interventions. These methods (which allow reaching the goals of the study) are considered following the previous study on Lima Metropolitan areas [1].…”

The seismic retrofitting of essential facilities is a typical problem of public administrations. Due to the large amount of existing and/or historic buildings with a high seismic vulnerability and the limited economic resources, it is necessary to provide efficient solutions for the structural reinforcement of these structures on a national, regional, and urban level. This paper proposes an innovative and multidisciplinary framework to choose massive interventions on a large territorial scale according to the potential benefits of the intervention in terms of reduction in expected economic losses associated with retrofitting intervention and other important aspects usually neglected in intervention strategies. The proposed framework is based on Multi-Criteria Decision-Making (MCDM) analysis. It is applied to a very complex urban area: the case study is the school buildings stock (4458 buildings) in the Lima Metropolitan area, Peru. The goal of the study is arisk analysis aimed at selecting the optimal retrofitting strategy in a huge urban area. The results of this work can be considered the base for decision-makers. They could use them as a decision support tool in the seismic risk mitigation on a large territorial scale.

“…Previous studies of seismic vulnerability of educational institutions follow one of two directions (i) evaluating the damages determined by specific earthquakes [4], [5]; or (ii) estimating the possible damages that may be caused by a future seismic event [6]- [15]. Also, there is an extended scientific literature volume regarding the matter of retrofitting of school buildings [16]- [22].…”

Multi-Criteria Assessment of the Seismic Vulnerability of School Units in Vaslui City, Romania

2020

In the context of an earthquake impact, school units are particularly vulnerable because of the specific age group of the population that studies there. This means that the earthquake mitigation strategies targeting schools should be carefully elaborated, starting from a proper assessment of their seismic vulnerability. Such assessments should be extensively conducted, especially in the case of urban settlements that are disadvantaged in terms of economic potential, social development and media image, like Vaslui City, Romania. This paper aims to evaluate the seismic vulnerability of school units in Vaslui City using a combination of Multi-Criteria Decision-Making (MCDM) methods and Geographic Information System (GIS) techniques. Unlike other assessments of this type, the proposed framework integrates both aspects related to the physical vulnerability of the school buildings, and social elements concerning the educational personnel, the age profile of the pupils, school hours and other factors. The methodology also includes a systemic vulnerability component that offers better insights about the access emergency services would have to the educational institutions in case of a powerful earthquake. The physical, social and systemic vulnerability factors/criteria are weighed via Analytic Hierarchy Process (AHP), while the 25 school units in the study area are evaluated using Weighted Product Model (WPM). The results are combined with GIS techniques in order to obtain a map that shows the seismic vulnerability level of the school units. The most vulnerable school units are the ones with tall old buildings located along narrow streets, with significant number of very young or disabled pupils. These findings represent the stepping stones for the retrofitting works and the educational programmes related to seismic hazards that should be implemented by local authorities. Although restricted by the low number of educational institutions in the study area, the proposed framework may be further on used in seismic vulnerability research.
