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.
