“…The cadastral limits of the building stock surveyed by Tertlliani et al (2011) were then digitized, with a total of 2142 buildings (s0), a bigger sample than the original one (sT = 1700 buildings). As such dataset did not include a detailed characterization of the buildings inspected, further studies were performed by the Earthquake Damage Analysis Center (EDAC -Bauhaus-Universität Weimar) to collect, with the same tools, detailed characteristics of the buildings following the scheme proposed by Schwarz et al (2018).…”

“…Additionally, it can be discussed whether the same scale used to evaluate a global damage grade can be used to evaluate the damage at an element-wise level, as the Da.D.O. scheme does, or if future discussions are needed to develop an EMS-98 complementary scheme where the "LEGOisation" of a structure is to be taken as basis for an element-wise damage assignment as proposed by Schwarz et al (2018) and briefly addressed in case of masonry structures by Cattari & Angiolill (2022).…”

“…Further on, it can be said that the numerical scale used to describe the extension of damage tries to fill the void marked by the absence of criteria to describe the damages that particular structural elements can have and their interaction when a global assessment is performed. As addressed by Schwarz et al (2018), the idea from the damage scheme implemented by the AeDES form supports concept on which a building is composed by different zones (e.g., storeys) and structural elements (e.g., piers and spandrels in masonry, beams and columns in reinforce concrete) that would receive different damages, but can be integrated into a final global assignment. However, for the AeDES form, this is not the final goal and no further detail nor global description of damage are pursued.…”

Within the European TURNkey project, a knowledge-based exposure-modelling framework was developed enabling the consideration of different levels of investigation and data availability. In particular, the proposed framework recognizes various levels and origins of uncertainties as well as the completeness of a building stock catalogue. Despite enormous efforts, the main question remains unanswered: How reliable could be the developed tools and instruments if they are not tested and confirmed by real events. The L’Aquila 2009 earthquake has been subject of several analysis strategies to enrich the knowledge of earthquake engineering. In the present, the information provided by Italian Observed Damage Database is analyzed, specifically the data related to the L’Aquila 2009 seismic sequence, within the delimited area of the historical center of the city. A second source where the European Macroseismic Scale was used as reference is hereby integrated to the study and results are compared. A methodology is implemented for a systematic evaluation of database, taking as basis the EMS-98. From the data analysis a proposal is given to define a comparable EMS-98 building typology and for the assignments of vulnerability classes considering an optimistic, pessimist and most likely criteria. The reliability of the sample is then explored taking as basis the Knowledge-based exposure modelling framework established by the TURNkey Project, and the parameter is evaluated through an empirical inspection of frontal (lateral) views available in Google Street View (2022). Images before and after the event are collected and compared with the available data. Intrinsic encountered problems are then enlisted and discussed, with respect to the use of the database, the correlation of the information and the postprocessing needed to use the data in damage prognosis. This paper intends to demonstrate how reliable datasets for the building stock including structural types and corresponding vulnerability classes can be elaborated. Not at least, the exposure modelling has to transform the available data into a descriptive form that can be linked with the Fragility and/or Vulnerability Functions, directly with the expectation that these assignments are the best suited or representative ones. The data layers provided by the study enable the test and train the applicability of the exposure modelling techniques for the selected event and target region.

“…The building stock of the city of Freital was documented on a microscale level using a coordinated parameter list, which was implemented in an updated version of the EQUIP building survey tool developed by EDAC (cf. [31,32]). The EQUIP (elaboration, qualification and interpretation) tool supports the documentation of building characteristics for subsequent detailed vulnerability analyses and damage modelling.…”

The floods in 2002 and 2013, as well as the recent flood of 2021, caused billions Euros worth of property damage in Germany. The aim of the project Innovative Vulnerability and Risk Assessment of Urban Areas against Flood Events (INNOVARU) involved the development of a practicable flood damage model that enables realistic damage statements for the residential building stock. In addition to the determination of local flood risks, it also takes into account the vulnerability of individual buildings and allows for the prognosis of structural damage. In this paper, we discuss an improved method for the prognosis of structural damage due to flood impact. Detailed correlations between inundation level and flow velocities depending on the vulnerability of the building types, as well as the number of storeys, are considered. Because reliable damage data from events with high flow velocities were not available, an innovative approach was adopted to cover a wide range of flow velocities. The proposed approach combines comprehensive damage data collected after the 2002 flood in Germany with damage data of the 2011 Tohoku earthquake tsunami in Japan. The application of the developed methods enables a reliable reinterpretation of the structural damage caused by the August flood of 2002 in six study areas in the Free State of Saxony.

International liegen verschiedene Klassifikationsschemen für die Bewertung von Bauwerksschäden infolge der unterschiedlichen Naturgefahren vor. Diese sind aufgrund ihrer Heterogenität nur unzureichend für die Betrachtung von Schäden im Sinne eines Multi‐Hazard‐Ansatzes geeignet. Für die Bewertung der Verletzbarkeit von Bauwerken gegenüber verschiedenen Naturgefahren und die Prognose von Schäden ist eine vereinheitlichte Systematik erforderlich, mit der wiederholt beobachtete Schadensbilder in ein Schema von Schadensgraden überführt werden können. Mit diesem Instrumentarium kann der Schaden einheitlich ausgewertet und der Zusammenhang zu den Einwirkungskenngrößen hergestellt werden. Dabei wird dem Vorgehen der European Macroseismic Scale 1998 (EMS‐98) für Erdbebenschäden gefolgt, indem zwischen strukturellen und nicht strukturellen Schäden unterschieden wird, denen in Form von Schadensgraden charakteristische Schadensbilder zuordenbar sind. Es wird ein allgemeines Klassifikationsschema für Bauwerksschäden vorgestellt, mit dem eine Vergleichbarkeit der Schäden infolge der einzelnen Naturgefahren hergestellt werden kann. Auf Grundlage real beobachteter Schadensfälle werden die typischen Schadensmuster für die Naturgefahren Hochwasser, Tsunami und Wind herausgearbeitet und in aufeinander abgestimmte Schadensgrade klassifiziert. Mit den eingeführten Schadensskalen steht erstmals ein Instrumentarium zur Verfügung, um Schadensfälle an einem Gebäudebestand infolge unterschiedlicher Naturgefahren nach ingenieurmäßig vereinheitlichten Kriterien bewerten zu können. Im Ausblick steht die Prognose der Schäden infolge der unterschiedlichen Naturgefahren und ihrer möglichen Abfolgen.
