## Abstract Tubular space trusses for bridge applications use thickβwalled tubes. The reduction in fatigue resistance due to geometrical size effects is thus an important issue. In order to carry out a thorough study, both fatigue tests on largeβscale specimens and advanced 3D crack propagation mod
Welded circular hollow section (CHS) joints typical to bridge construction have been examined in an experimental, numerical, and analytical study with respect to their fatigue strength. Evidence from this study has indicated lower fatigue strength for joints with thicker failed members. A re-examina
In the past, several methods have been proposed to predict fatigue crack growth rate in tubular joints of offshore structures, however reasonably accurate solution for this problem is still lacking. Dramatic increase in the use of neural neural networks (NN) in material science, specially fatigue ar
