Title:
Abstract:	Angesichts der dichten Besiedlung kommt dem Schallschutz an Verkehrswegen in Deutschland eine große Bedeutung zu. Insbesondere an Eisenbahnstrecken kommen Lärmschutzwände aus Stahlbetonfertigteilen zum Einsatz. Bei Hochgeschwindigkeitsverkehr führt die Belastung aus Zugvorbeifahrt zu Schwingungen der Wände, sodass die Ermüdungsfestigkeit nachgewiesen werden muss. Im Labor des Instituts für Konstruktiven Ingenieurbau der Universität der Bundeswehr wurden hierzu in den vergangenen Jahren zahlreiche Versuche mit zyklischer Belastung durchgeführt. Dabei wurde dem Auflagerbereich, angesichts der sehr kleinen Auflagerbreite, besondere Beachtung geschenkt. Reinforced Concrete Precast Panels as Noise Protection along High Speed Rail Tracks The noise protection along traffic routes has large importance in Germany due to the high density of population. Reinforced concrete panels as noise protection walls are often used especially along railroad tracks. The loading due to high-speed trains induces oscillation of the walls and the fatigue, therefore, has to be investigated. During the last years, the Laboratory of the Institute of Structural Engineering at the University of the German Armed Forces in Munich performed a large number of tests involving cyclical loading. The particular area of interest was the relatively narrow support.
