- Abstract
The 2021 flood: engineering analysis of building damage The flood event of July 2021 left extremely severe structural damage to the general buildings and infrastructure especially in the affected areas of Rhineland‐Palatinate and North Rhine‐Westphalia. The article gives an overview of the results of a damage documentation that was carried out immediately after the flood in the Ahr valley and Bad Münstereifel. The survey continues a line of flood damage analyses carried out over the past 20 years by the Earthquake Damage Analysis Center at the Bauhaus‐Universität Weimar, which has resulted in the development of an engineering‐based flood damage model that can takes into account such severe structural damage. With the documentation of the damage, the knowledge gained by EDAC about the behavior of the various building types under the influence of extreme flooding conditions could be deepened and checked for plausibility. The flood damage patterns found confirm the approaches of the EDAC flood damage model and show the need for an extension to take into account the special features of the building stock and the flooding conditions that occurred. A connection is given to ongoing studies, in which drone‐based techniques for rapid assessment of the status of areas affected by a natural disaster and the existing buildings are presented with the aim of generating realistic and easily interpretable situation images.
