“…Diese wurden auch im europäisch geförderten MATRIX‐Projekt als Modell für die Auswertungen übernommen. In Modell 3 wurden die Ansätze für die Verletzbarkeitsfunktionen der Modelle 1 und 2 nochmals modifiziert. Es kam bei der Re‐Interpretation der Schäden des Albstadt‐Erdbebens , für die Modellstudie Baden‐Württemberg und im Rahmen internationaler Projekte erfolgreich zum Einsatz.…”

International liegen verschiedene Schadensmodelle vor, um die strukturelle Schädigung des Bauwerksbestands und die daraus resultierenden Verluste infolge Erdbebeneinwirkung zu quantifizieren. Die Anwendung der verschiedenen Schadensfunktionstypen für eine realitätsnahe Ermittlung der Schäden setzt eine detaillierte Kenntnis des Bauwerksbestands und seiner Verletzbarkeit sowie der standortspezifischen Untergrundbedingungen voraus. Das am Zentrum für die Ingenieuranalyse von Erdbebenschäden der Bauhaus‐Universität Weimar im Rahmen des Deutschen Forschungsnetzes Naturkatastrophen (DFNK) entwickelte intensitätsbasierte Schadensmodell für die allgemeine Bebauung wurde an den gemeldeten Verlusten des Albstadt‐Erdbebens von 1978 validiert. Eine Betrachtung der Streubreiten und Unsicherheiten in der Verteilung der Schadensgrade Di sowie die Spiegelung an vergleichbaren Schadensmodellen stand bisher noch aus. Die Re‐Evaluation der untersuchten Modellansätze erfolgt im Beitrag an den durch unterschiedliche Standortintensitäten gekennzeichneten Erdbebenereignissen (Albstadt 1978, L'Aquila 2009) anhand der real aufgetretenen Bauwerksschäden. Im Rückblick auf die DFNK‐Studie werden die Ergebnisse für den Großstadtraum Köln nochmals mit neuen Bauwerksdaten und dem erweiterten Schadensmodell überprüft. Die im DFNK aggregiert beschriebene Bauwerksverletzbarkeit wird auf den Einzelbauwerksbestand übertragen und der Einfluss auf die Erdbebenszenarien untersucht. Die Streuung der strukturellen Schäden und der Verluste wird durch Monte‐Carlo‐Simulationen berücksichtigt. Die Veränderungen der Ergebnisse gegenüber der DFNK‐Studie werden ausgewiesen und diskutiert.

“…The application of risk-oriented taxonomies is appropriate for developing exposure models that are based on either an expert judgment [41], a combination of data compiled by authorities (e.g., census data), or a field data collection [42], where each of the inspected buildings is assigned one of the predefined group of building classes in compliance with the surveyor's personal judgment.…”

Due to increases in the number of inhabitants and their concentrations in densely populated areas, there is a growing need in modern society to be cautious towards the impact of catastrophic natural events. An earthquake is a particularly major example of this. Knowledge of the seismic vulnerability of buildings in Europe and around the world has deepened and expanded over the last 20 years, as a result of the many devastating earthquakes. In this study, a review of seismic risk assessment methods in Croatia was presented with respect to the hazard, exposure, and vulnerability of buildings in the fourth largest city (Osijek) in Croatia. The proposed algorithm for a detailed risk assessment was applied to a database and is currently in its initial stage.Sustainability 2020, 12, 1796 2 of 24 to estimate the losses. These losses can be assessed in a material form, through the damage of the building stock or non-structural elements of buildings, or in the form of casualties or injuries during the earthquake [10,11]. The last step is to analyze uncertainties, costs, decision-making criteria, etc. The ultimate goal of studying earthquakes and their impact on people and buildings is to create a safer environment, in case an earthquake occurs.The basic elements of the earthquake risk assessment process are shown in Figure 1.Sustainability 2020, 12, 1796 2 of 25 probable intensity in a given geographical area). Then, based on the available data from the exposure model, evaluate the damage using one of the existing vulnerability assessment methods in order to estimate the losses. These losses can be assessed in a material form, through the damage of the building stock or non-structural elements of buildings, or in the form of casualties or injuries during the earthquake [10,11]. The last step is to analyze uncertainties, costs, decision-making criteria, etc. The ultimate goal of studying earthquakes and their impact on people and buildings is to create a safer environment, in case an earthquake occurs. The basic elements of the earthquake risk assessment process are shown in Figure 1.

“…They mainly describe and classify buildings according to their earthquake resistance, structural response to earthquakes and earthquake risk assessment. The use of these taxonomies is possible when the exposure models based on in-situ data collection are developed [33] or when credible data (e.g., from a census) and expert judgment are combined [34].…”

Development of Seismic Vulnerability and Exposure Models—A Case Study of Croatia

et al. 2020

View full text Add to dashboard Cite

Assessing earthquake risk and building vulnerability requires an exposure model. These exposure models quantify the building stock in terms of structural characteristics, spatial location, and occupancy. The most significant exposure parameters are the structural characteristics of buildings, which must be uniformly covered by structural typologies. Structural typologies that take into account the regional specificities of design and construction provide more accurate and reliable exposure models. Despite the long history of earthquake engineering in the Republic of Croatia, the assessment of exposure and vulnerability of buildings is a rather new concept, hindered by the fact that no city in the Republic of Croatia has a database on the number, types, and characteristics of existing buildings. The article presents the creation of a building exposure model for the city of Osijek, points out the problems and concerns that the realization process brings, and details the practical solutions and strategies that have been used to achieve the set goals.
