Abstract:	Mobile Großgeräte sind für die globale Wirtschaft von großer Bedeutung. Zunehmend werden sie aufgrund immer knapper werdender Rohstoffe in seismisch aktiven Gebieten, in denen noch Vorräte schlummern, eingesetzt. Das seismische Verhalten dieser nicht verankerten Strukturen unterscheidet sich durch die Möglichkeit des Abhebens grundlegend von konventionellen Bauwerken und eine zutreffende und wirtschaftliche erdbebengerechte Auslegung ist nach derzeit geltenden Erdbebennormen weltweit kaum möglich. In diesem Beitrag wird das Verhalten typischer schienengebundener mobiler Großgeräte der Fördertechnik bei Erdbeben am Beispiel von Schaufelradgeräten exemplarisch in seinen Grundsätzen untersucht, analysiert und daraus resultierend grundsätzliche Bemessungsempfehlungen für schienengebundene mobile Großgeräte der Fördertechnik gegeben. Das numerische Berechnungsmodell wird anhand von Schwingungsmessungen an realen Geräten validiert. Basic investigation of the seismic behavior of large material handling equipment using the example of a rail-bound stacker-reclaimer - Part 2: Seismic analysis and validation Large mobile equipment is of great importance to the global economy. Due to ever scarcer raw materials it is increasingly being used in seismically active areas where reserves are still dormant. The seismic behavior of these non-anchored structures differs fundamentally from conventional structures due to the possibility of lift-off, and an accurate and economical seismic design according to current earthquake standards worldwide is hardly possible. The seismic behavior of typical large rail-bound mobile material handling equipment using the example of stacker-reclaimers is basically investigated and analyzed in this paper. As a result, basic design recommendations for large rail-bound mobile material handling equipment are given. The numerical analysis model is validated by means of vibration measurements on real stacker-reclaimers.
