Weld fatigue life using different international standards

  • AISC LRFD Tables (US)
  • AISC ASD Tables (US)
  • AASHTO Tables (US)
  • BS7608 Tables (UK)
When assigning Stress Categories or Fatigue Classifications pay lawyer-like attention to the qualifying notes.

Factors effecting weld fatigue life:
  • Stress concentration effects in the weld detail
  • Residual stress alters the mean stress and stress ratio.
  • These effects are secondary compared to stress range
  • AWS, EC3 and BS7608 assume that the actual stress experienced at a weld operates with an upper limit of the yield stress as the assume that yield strength residual stresses are always present in welds.
  • BS7608 allows a benefit for stress relieving heat treatment which promotes relaxation of residual effects.
  • Even if the load cycle is part compressive – parts of the weld only feel tensile stress over the whole load cycle.
  • The maximum stress at weld toe is always near the yield stress.

This calculation is used as a resource for our two day training course designed to help practising engineers understand and avoid fatigue failure in welded structures. Download the course brochure and syllabus here.

SUMMARY: The course uses real world case studies to understand the engineering principles governing fatigue failure of welded structures. We reduce complex mathematics to simple hand calculations using Excel workbooks so that engineers at all levels can understand the concepts covered. Engineers will leave understanding how to apply the AWS rules for fatigue design and will pick up new engineering and Excel skills along the way. It focuses on American AWS methods of fatigue assessment but the material equally covers BS7608 and Eurocode methods.

The download isnt working correctly. I have installed the XLC addin but still doesnt work. I have windows 10 64-bit. Any help would be appreciated.
