Course Content

Fatigue of steel members and connections can lead to damage to structures and potentially catastrophic failure. Fatigue failure can often be hidden from view and needs careful attention both in the design stage and fabrication stage to avoid issues. Whether it is in the mining or commercial building sectors, fatigue plays a part. For example, it has been stated that more than 75 percent of failures in welded components are due to fatigue. 

This course aims to provide attendees with an understanding of basis of fatigue analysis to AS 4100 and introduce other international design codes where the geometry is outside its scope. It is therefore a must-take course for structural engineers, mechanical engineers, forensic engineers and welding engineers.
