Abstract
: This research concentrates on examining the fatigue behaviour of stainless-steel bridges and the influence of diverse edge profiles on the fatigue life of welded joints. Fillet-welded joints are specifically studied due to their common occurrence in load-bearing elements susceptible to fatigue damage. The investigation delves into the impact of various edge profiles, encompassing concave shapes with different arc radii, chamfering with varying radii, and the positioning of the edge profile relative to the sample profile. Utilizing numerical simulations, the analysis reveals that the fillet profile with a 140 mm radius on the perpendicular side demonstrates the highest joint lifespan compared to other profiles. This discovery underscores the substantial role that the selection of an edge profile can play in determining the fatigue performance of welded joints in stainless-steel bridges. Given the recent advancements in the design and construction of stainless-steel bridges, the outcomes of this research hold significant relevance.
