The Fatigue Performance of Angle Cross-Frame Members in Bridges

Geoffrey Scott McDonald, Karl H. Frank


This study investigated the fatigue performance of welded angle cross-frame connections and the factors affecting the fatigue life of these members. The type of cross-frame used in this analysis is one of three typical cross-frame connection details. Other connection details include using WT or Channel sections as cross-frame braces, however, angle cross-frames are the most common connection detail and will be the only cross section considered in this research.
