Comparison of tubular joint strength provisions in codes and standards

Presents a comparison of fatigue provisions, covering general aspects, including the overall approach taken to fatigue assessment, safety factors, and modifications to S-N or fatigue strength curves (eg for thickness effects and weld improvement). The S-N curve parameters are itemised for each document and comparisons between the curves made for joints in air, in seawater with adequate corrosion protection, and in seawater with free corrosion. Comparisons for nodal tubular joints and cast joints are given separately.
