“…3 APPLICATION This application consists of performing an earthquake scenario in the urban area of Constantine city (see Fig. 4), located at the North-East of Algeria [15], which will allow the building seismic damage assessment of this city. For that, an extensive inventory of almost 31000 building units was carried out by the National Earthquake Engineering Research Centre (CGS), within the framework of the study of vulnerability and evaluation of the seismic risk of this city.…”

This contribution focuses on the adaptation and application of RADIUS methodology (Risk Assessment Tools for Diagnosis of Urban Areas Against Seismic Disaster) integrated with a Geographic Information System (GIS) to the Algerian context for the seismic vulnerability evaluation in urban areas potentially exposed to earthquakes. Within this framework, this application aims to perform a probable earthquake scenario in the urban centre of Constantine city, located at the North-East of Algeria, which will allow the buildings seismic damage estimation of this city. For that, an extensive inventory of almost 31,000 buildings was carried out. The simulation of the expected building seismic damage and the generated GIS damage maps provides a predictive evaluation of the damage that can occur due to a potential earthquake near to Constantine city.The theoretical forecasts are considered important for decision makers in order to reduce building vulnerability, to take adequate preventive measures and to develop suitable strategies for prevention and emergency management plans to reduce the losses. They can also help to identify the most damaged areas in the early moments following an earthquake to take the adequate emergency measures.

“…Their results were consistent with the historical and modern evolution of the populated area, showing the validity and strength of both methods. Recently, Boukri et al [8] provided predicted the seismic risk and damage for buildings in Constantine, Algeria, adapting their methodology of assessing building damage from the HAZUS approach.…”

“…A comprehensive typology of buildings in Europe has been developed as part of the Risk-UE Project (2001)(2002)(2003)(2004), which distinguishes 17 types of buildings divided into three subclasses based on building height (low, medium, or high) and the seismic zone in which the building is located [8]. The European typology distinguishes three earthquake zones: Zone I, whose MMI (modified Mercalli scale) equals or exceeds earthquake intensity VIII; Zone II, which corresponds to MMI earthquake intensity VII; and Zone III, which corresponds to earthquake intensity VI.…”

The Croatian territory, as part of the Mediterranean-trans-Asiatic belt, experiences pronounced earthquake activity. Seismic risk is the expected damage caused by earthquakes to buildings, measured both in social and economic losses, which can be described through seismic hazard, seismic vulnerability, and exposure. The city of Osijek is located in the eastern part of Croatia, and Retfala Nova is a residential settlement in the western part of the city. An important step in assessing earthquake loss is defining the exposure, so we created a form used to collect information on buildings and make a building database. In this paper, we estimated seismic vulnerability based on the capacity spectrum method, which involves constructing fragility curves and converting them to damage probability matrices, as well as constructing capacity curves.Sažetak: Područje Republike Hrvatske, kao dio mediteransko-transazijskog pojasa, odlikuje se izraženom potresnom aktivnošću. Potresni rizik predstavlja očekivani stupanj oštećenja građevina nakon potresa. Može se jednostavno opisati kroz četiri elementa: potresnu opasnost, potresnu oštetljivost, izloženost zgrada, te socijalne i ekonomske gubitke. Grad Osijek nalazi se u istočnom dijelu Republike Hrvatske. Retfala Nova je stambeno naselje smješteno u zapadnom dijelu grada. Budući da je bitni element u procjeni potresnog rizika izloženost, predložili smo obrazac koji će služiti kod stvaranja baze zgrada grada. U ovome radu potresna oštetljivost procijenjena je pomoću metode zasnovane na spektru sposobnosti nosivosti, koja podrazumijeva konstruiranje krivulja vjerojatnosti oštećenja i njihovu pretvorbu u matrice vjerojatnosti oštećenja, te konstruiranje krivulja sposobnosti nosivosti. Ključne riječi: potresni rizik; potresna oštetljivost; krivulje vjerojatnosti oštećenja; tipologija zgrada Number 11, Year 2015 Page 50-61 Assessing seismic risk in Retfala Nova, Osijek Galista, M, Hadzima-Nyarko, M http://dx.

“…On the other hand, several studies has also been carried out in order to reduce the seismic vulnerability of buildings [1,2,3,4,5,6,7] as well as reducing the seismic risk in urban areas [8,9,10,11,12,13]. These studies highlighted, through seismic scenarios, the towns response located in seismic zones [14,15,16]. After each major earthquake that struck in different regions in the world, (Kobe, Japan 1995 or Boumerdes, Algeria 2003) economic and human losses were recorded, going as far as the paralysis of the functionality of these cities.…”

Several studies have been carried out to assess the building’s seismic vulnerability, in order to mitigate the seismic risk in urban areas, which is one of the most devastating natural hazards causing considerable economic and human losses. These studies must be incorporated to improve the planning of urban areas in order to have resistant and resilient cities in case of disasters. The seismic feedback has shown that the build back better concept has a direct impact on the city’s economic growth. In this paper, the existing buildings resilience is assessed, in order to highlight the capacity of these last to keep the functionality when an earthquake occurs. This building’s resilience has been determined according to the damages states, the reconstruction time and the reconstruction cost for three types of structures: masonry, reinforced concrete and steel. The vulnerability curves used give the damage grade according to the vulnerability index and the seismic intensity. A seismic resilience scenario was performed using a geographic information system (GIS) and applied for the Blida city (Algeria) classified as a high seismic zone according to Algerian seismic regulations.
