Title:	Planung von Turbinenfundamenten in Erdbebengebieten
Abstract:	Dieser Beitrag stellt grundsätzliche Prinzipien elastisch gelagerter Systeme und Anwendungen im Bereich der Kraftwerksausrüstung und von Gebäuden in mittleren und hohen Erdbebenzonen dar. Kombinierte Feder-Dämpferelemente mit speziellen Steifigkeitseigenschaften werden eingesetzt, um die seismischen Beschleunigungswerte der Turbinenkomponenten und weiteren sicherheits- oder nicht-sicherheits relevanten Strukturen zu reduzieren. Für Turbinengebäude kann die Integration der Unterkonstruktion des Turbinendecks in das Maschinenhaus zusätzlich sowohl die relative Verschiebung zwischen den beiden Strukturen als auch den Spannungslevel in allen Bauteilen reduzieren. Design of Turbine Foundations in Seismic Zones - Earthquake Protection Strategies. This contribution reveals basic principles of elastic support systems and applications on power plant equipment and buildings in medium and high seismic areas. Spring-damper combinations with special stiffness properties are used to reduce seismic acceleration levels of turbine components and other safety or non-safety related structures. For turbine buildings, the integration of the turbine substructure into the machine building can additionally reduce the relative displacement between both the structures as well as the stress levels in all structural members.
