Fatigue behavior at flange thickness transitions with cope holes – design model for engineering practice Open
Flange thickness transitions are common constructional details in welded girders, such as crane runway girders or main girders of highway and railway bridges, to adapt the bending moment capacity of the girder to variable bending moment di…

Fatigue behavior of girder with flange thickness transitions and cope holes ‐ tests and simulations Open
The fatigue behavior of steel girders with flange thickness transition and cope hole has been experimentally analyzed with two large‐scale cyclic tests. Special attention is paid to the arising and interacting local effects. The fatigue te…

Fatigue Life Prediction of Welded Girders with Flange Thickness Transitions and Cope Hole Open
The paper presents an analytical and numerical approach for the fatigue life prediction using local concepts. A Two‐Stage‐Model is applied to a welded girder with thickness transition and cope hole to determine its fatigue life. The model …

TWO‐STAGE‐MODEL FOR THE PROGNOSIS OF FATIGUE LIFE: APPLICATION TO BUTT WELDS Open
This paper presents a Two‐Stage‐Model to determine the fatigue life. The model follows the distinction between the crack initiation and the crack propagation according to the phenomenological background. The first stage uses the local notc…
