AS 4100 Fatigue (2020)

The AS 4100 Fatigue (2020) implementation in SDC Verifier enables verification of fatigue strength according to the Australian steel design code. The standard extends the existing AS 4100 framework with hot spot stress calculation and rainflow counting, covering fatigue-critical structural components. 

Scope of Application: 

• Steel members and welded connections in fatigue-sensitive structures 

• Hot spot stress extraction at weld toes 

• Rainflow cycle counting for variable amplitude loading 

• Application in cranes, lifting equipment, and industrial steel frameworks 

Key Features: 

• Direct use of FEA stress results for hot spot determination 

• Automated cycle counting (rainflow method) for fatigue assessment 

• Supports multiple loading histories and spectrum inputs 

• Fatigue checks integrated with other AS 4100 strength and stability verifications 

Highlights for Engineers: 

• No need for external fatigue post-processing 

• Configure fatigue categories and safety factors according to AS 4100 

• Generate detailed fatigue plots and reports with cycle counts and hot spot utilization
