Analysis of Fatigue Crack Propagation in Steel I-Beams with Welded Transverse Stiffeners Subjected to In-Plane Loadings [PDF]
, 2017 Fatigue crack propagation represents the mechanical damage that shortens the service life of bridge structures. Most fatigue cracks initiate at the welded details due to geometric discontinuities, residual stresses and initial weld defects.
