F.E.M. 1.001 (3rd, 1998)

F.E.M. 1.001 (3rd edition, 1998) is a guideline by the Fédération Européenne de la Manutention for the design and verification of steel structures in hoisting appliances and cranes. It combines static stress validation with a detailed fatigue assessment based on the Allowable Stress Design (ASD) method.

Implemented in SDC Verifier:

• Static stress check (Section 3)
• Fatigue check and summation (Section 4)
• Based on weld type, load spectrum, and number of cycles
• Supports classification tables for crane duty group selection (Element Group E1–E8)
• Compliant with St37 and St52 steel material types

Fatigue classification is defined by:

• 🔧 Weld Type (Notch Case): K0–K4 (welded), W0–W2 (non-welded)
• ⚙️ Load Spectrum: P0–P3 (very light to heavy usage)
• 🔁 Utilization Class (Cycles): B0–B10 (≤16,000 to 8 million+ cycles)

Key Features:

• Safety factor control per load case
• Optional hot spot stress or weld stress-based fatigue
• Rainflow counting and summation across load groups (Enterprise license)
• Combined utilization factor calculated for multi-axial stress directions

F.E.M. 1.001 is especially useful in verifying lifting equipment, bridge cranes, hoist systems, and offshore handling devices exposed to repeated loading.
