Title:
Abstract:	Kämme für Kreuz- und Eckverbindungen sind wesentliche Bestandteile nahezu jedes zimmermannsmäßig errichteten Holztragwerks in Mitteleuropa. Die Anwendung dieser Verbindungen als statisch tragende Anschlüsse nach EN 1995-1-1 bedarf der Kenntnis der mechanischen Kenngrößen. Umso erstaunlicher ist es, dass in der Literatur bislang Angaben zur Tragfähigkeit und insbesondere zum Verformungsverhalten fehlen. In diesem Beitrag werden 26 zerstörende Prüfungen an unterschiedlichen Kammverbindungen und deren Auswertungen vorgestellt. Sowohl für die Bemessung dieser Verbindungen als auch für die Ermittlung der Steifigkeiten - abgeleitet aus dem Verformungsverhalten - werden Berechnungsvorschläge angegeben. Load-bearing capacity and load-bearing behaviour of notched joints Cross and corner joints using notches are important members of almost every roof structure 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. It's even more astonishing, that therefore codes and literature lack information. This contribution deals with 26 tests of different notched joints and their results. Both proposals for the design and for the determination of the stiffnesses of these joints are given here.
