Abstract:	In diesem Beitrag wird die Verwendungsmöglichkeit axial beanspruchter Verbindungsmittel in Fachwerkträgern aus Buchenfurnierschichtholz mithilfe experimenteller Untersuchungen genauer betrachtet. Die zur Bemessung benötigten Festigkeits- und Steifigkeitskennwerte und die notwendigen konstruktiven Randbedingungen (Mindestabstände, Einbindelänge) werden ermittelt, diskutiert und mit dem derzeitigen Stand der Technik verglichen. Zur Verifizierung der ermittelten Parameter sowie des Tragverhaltens der untersuchten Verbindungsmittel in Gesamttragsystemen werden im Anschluss Versuche an Fachwerkträgern (Spannweite 10 m, statische Höhe 1,25 m) mit unterschiedlichen Knotenpunktausbildungen vorgestellt. Besonderes Augenmerk wird, neben der Tragfähigkeit, auf die Steifigkeit der geprüften Träger gelegt und somit die Leistungsfähigkeit der vorgestellten Verbindungsmittel herausgearbeitet. Trusses made of beech-LVL The suitability of axially loaded fasteners in trusses made of beech-LVL is studied by experimental investigations. The strength and stiffness properties and the structural boundary conditions (minimum distances, penetration length) are determined, discussed and compared with the state of the art. To verify the parameters as well as the load-bearing behavior of the investigated fasteners, results of full-scale tests with trusses (span 10 m, static height 1.25 m) with different node configurations are presented. In addition to the load-bearing capacity, the stiffness of the tested trusses is under special attention to clarify the performance of the presented connections.
