The Crane-Supporting Steel Structures: Design Guide, 4th Edition (2021)
4.3 Elevated Runway Systems (Freestanding)
For facilities where the crane is not integrated into the main building, the guide provides provisions for freestanding columns and trusses. This section Detailing and Connection Design : Step 4: Fatigue
Detailing and Connection Design:
Step 4: Fatigue Analysis (AISC 360-16 Appendix 3)
- Identify all fatigue-critical details (plates, welds, holes).
- Compute nominal stress range at each detail.
- Compare to threshold stress range (ΔF_th) for the appropriate detail category.
- If ΔF > ΔF_th, redesign connection or reduce stress range.
