EN 13001 Fatigue (2018)

EN 13001 Fatigue (2018) covers crane safety design according to the European standard EN 13001-3-1+A2, specifically focusing on steel structure fatigue verification and static strength assessment.

This standard applies the Limit State Method as the default for both static and fatigue strength evaluations, with the Allowable Stress Method permitted in specific linear cases. It accounts for stress history, fatigue group classification, notch sensitivity, weld orientation, and material-specific resistance factors.

Key capabilities in SDC Verifier:

• Static Strength:
  • Calculates limit design stress for normal and shear stresses using material data and resistance factors
  • Includes optional allowable stress method with user-defined safety factors
• Fatigue Strength:
  • Supports both direct stress history and simplified fatigue evaluation methods
  • Stress history parameter computed from spectrum data
  • Includes fatigue strength specific resistance factor (γmf), notch class, slope factor, and reduced stress range
• Additional features:
  • Weld stress and Hot Spot stress integration
  • Rainflow Counting method available (Enterprise license only)
  • Detailed support for classification of welded and non-welded joints
  • Plane stress correction, effective stress range handling, and UI for Notch Class configuration

This implementation is critical for structural engineers validating crane components against fatigue failure over design life cycles and is based entirely on EN 13001-3-1 Annexes and tables.
