Title:
Abstract:	Blätter für Winkel- und Kreuzverbindungen sind wesentliche Bestandteile vieler zimmermannsmäßig errichteter Holztragwerke in Mitteleuropa. Die Anwendung dieser Verbindungen als statisch tragende Anschlüsse nach EN 1995-1-1 bedarf der Kenntnis ihrer Tragfähigkeit und ihres Verformungsverhaltens. In der Normung und Literatur fehlen hierzu Angaben. Im vorliegenden Beitrag werden daher die Tragfähigkeit und das Verformungsverhalten von druckbeanspruchten Blättern (Winkelverbindungen, hier: Weißschwänze und Überblattungen) behandelt. Die Auswertung der Ergebnisse von 92 zerstörenden Prüfungen werden vorgestellt. Sowohl für die Bemessung dieser Verbindungen als auch für die Ermittlung der Federsteifigkeiten werden Berechnungsvorschläge angeführt. Load-bearing capacity and load-bearing behaviour of lap joints loaded in compression Angle and cross joints using laps are important members of a lot of roof structures erected by carpenters in central europe. The structural usage of these joints demands the knowledge of their load-bearing capacity and behaviour according to EN 1995-1-1. Therefore codes and literature lack information. This contribution deals with the load-bearing capacity and behaviour of lap joints (as angle joints, here: dovetail lap joints and halved joints) loaded in compression. 92 tests were performed and analysed. Both proposals for the design and for the determination of the stiffnesses of these joints are given here.
