“…Fragility curves of the investigated buildings in current state and with the four considered retrofitting techniques are defined using Peak Ground Acceleration (PGA) as the ground motion intensity measure (IM). Although other IMs have shown to produce more meaningful results (e.g.,Housner Intensity, Arias Intensity, Acceleration Spectrum Intensity, and Average spectral acceleration), PGA has been considered to comply with existing hazard data and vulnerability models developed over the years by different research groups for Lima Metropolitan area (e.g., [1][2][3]5,21]). Fragility curves of the investigated buildings in current state and with the four considered retrofitting techniques are generatedfollowing the procedure proposed by several authors [29].…”

Comparison of Different Intervention Options for Massive Seismic Upgrading of Essential Facilities

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.

“…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.…”

“…The uninterrupted functioning of such facilities is paramount for the operational continuity of a community or city. However, recent studies have underscored the high seismic risk associated with such constructions [16,17]. Consequently, the call for improving seismic capacity through appropriate modernization interventions has been emphasized.…”

This research, conducted in Zaruma, southern Ecuador, seeks to evaluate the seismic vulnerability and performance level of the Humberto Molina Hospital's reinforced concrete buildings. The study employs an examination of national and international seismic codes for rehabilitation, along with the implementation of recommended techniques. Structural characteristics of the buildings were identified through auscultation, surveys of reinforcing steel, and the extraction of concrete cores. The amassed data, coupled with a seismic hazard analysis of the site, facilitated a structural assessment of the blocks, conducted in accordance with national (MIDUVI) and international (ASCE/SEI) codes. The Federal Emergency Management Agency (FEMA) subsequently proposed rehabilitation alternatives for each block. Due to the importance of the hospital's functions, data collection was limited to blocks B3 and B4. The structural system, composed of moment-resisting concrete frames, exhibits potential vulnerabilities due to knocking (collision) and torsion, attributed to its irregular form. Structural evaluation revealed that block B4 adheres to the drift limits stipulated by the ASCE 41-13 standard (below 2%), while block B3 exceeds these limits (2.05-2.80%). Recommended rehabilitation strategies for B3 encompass mass reduction (removal of the second floor, representing a dead load of 700kg/m 2 and a live load of 200kg/m 2 ), and the introduction of additional rigidity and strength (extension of structural elements). For block B4, it is suggested that each sub-block be made independent. These interventions aim to facilitate the hospital's reopening, thereby benefiting the Zaruma Mining District community.

“…We selected Lima because it has a high seismic risk and it has recently built a unique data set containing high-resolution hospital vulnerability. We use city-wide data on the seismic vulnerability of >1.5 M buildings in Lima to estimate casualties and data including the seismic vulnerability of 41 public hospital campuses (composed of +700 buildings) and their respective operating rooms and ambulance resources 11 , 18 , 19 .…”

Effective plans for hospital system response to earthquake emergencies

Hospital systems play a critical role in treating injuries during disaster emergency responses. Simultaneously, natural disasters hinder their ability to operate at full capacity. Thus, cities must develop strategies that enable hospitals' effective disaster operations. Here, we present a methodology to evaluate emergency response based on a model that assesses the loss of hospital functions and quantifies multiseverity injuries as a result of earthquake damage. The proposed methodology can design effective plans for patient transfers and allocation of ambulances and mobile operating rooms. This methodology is applied to Lima, Peru, subjected to a disaster scenario following a magnitude 8.0 earthquake. Our results show that the spatial distribution of healthcare demands mismatches the post-earthquake capacities of hospitals, leaving large zones on the periphery significantly underserved. This study demonstrates how plans that leverage hospital-system coordination can address this demand-capacity mismatch, reducing waiting times of critically injured patients by factors larger than two.
