This study investigated the behavior of newly-developed circular steel girder over bridge. The traditional bridge is a simple span with the maximum span length about 7.0m. The proposed bridge is sequenced by extending a steel tube girder and reducing the number of infrastructure. It can make to improve constructability and save cost. In this study, we conducted a finite element analysis of the behavior of the main part, and aimed to check the compliance of allowable stress.
