Abstract:	Geschweißte Schienenklemmen werden in der Regel im Druckbereich von Kranträgern zur Befestigung der Schiene genutzt. Die Spannungsverhältnisse an Kranbahnträgern, besonders in Einfeld-Bauweise, sind dabei sehr ähnlich. Da für dieses Kerbdetail eine eindeutige Behandlung in den Kerbfallkatalogen der maßgebenden Normen bisher nicht erfolgte, wurden hier Untersuchungen durchgeführt, die eine Einstufung erlauben. Es zeigt sich im Vergleich zu ähnlichen Kerbdetails, wie etwa der Gurtlamelle, dass aufgeschweißte Schienenklemmen ein deutlich günstigeres Kerbverhalten aufweisen. Das gilt vor allem für Klemmen, die im Druckbereich der Träger aufgeschweißt wurden. Rolled sections with welded rail clamps - Fatigue behaviour under compressive stress. Welded rail clamps are usually used to fix the rail at the compression area of crane girders. Especially for single span beams, the stress ratios of crane runway girders are similar. For this notch detail, a clear classification in the standards is not available, so experimental investigations with the aim of a notch classification of this detail were executed. A comparison to similar notch details like the welded lamellas on beam belts shows, that welded rail clamps have an improved fatigue behavior, especially for clamps at the compression area of the girders.
