Finite Element Based Fatigue Evaluation of Cope Holes in Bridge Girders
Welded steel bridge girders frequently utilize cope holes at web-flange transitions to permit full welding of thick flanges and to eliminate any triple point welds. These cope holes (also referred to as 'rat' holes) are intended to be smooth and regular in shape. KsDOT requested a study to examine the fatigue behavior of cope holes specifically to answer the question as to which AASHTO fatigue category governs cope holes. The goal of this project is to supplement the AASHTO Bridge Design Specification by providing experimental and analytical information for designers as to how to categorize cope holes in welded steel girders.
