Title:
Abstract:	Die vorgenommene Neueinschätzung der Erdbebengefährdung für Deutschland im Rahmen der Erstellung des neuen Nationalen Anhangs zu DIN EN 1998-1 gab den Anlass, die in der geltenden DIN EN 1998-5 angegebene Nachweisführung zur Bodenverflüssigung zu bewerten und zu aktualisieren. In diesem Zusammenhang wurde für Gebiete mittlerer Seismizität ein leicht handhabbares Nachweisverfahren entwickelt, welches den aktuellen Stand der Technik berücksichtigt. Es basiert auf Ergebnissen von Drucksondierungen am Standort und erlaubt eine direkte Aussage zur potenziellen Gefährdung infolge Verflüssigung. Das Verfahren ist Bestandteil des neuen Nationalen Anhangs zu DIN EN 1998-5. Approximate method for verification against ground liquefaction in regions of medium seismicity according to DIN EN 1998-5/NA:2021 The re-assessment of the earthquake hazard for Germany as part of the preparation of the new National Annex to DIN EN 1998-1 gave the reason to evaluate and update the verification against soil liquefaction specified in the applicable DIN EN 1998-5. In this context, an easy-to-use calculation method was developed for regions of medium seismicity, which takes into account the current state of the art. It is based on the results of cone penetration tests at the site and allows a direct determination of the potential liquefaction hazard. The procedure is part of the new National Annex to DIN EN 1998-5.
