Abstract
A fish-bone type bridge is vulnerable to the torsional behavior due to the single girder system with planar zigzag conformation. The fixed connecting area between the girder and pier is the special weak point because the torsional load creates excessive stress concentration. Therefore, the method to reduce the stress concentration is required. In this study, the reduction efficiency of various reinforcing types to reduce the excessive stress occurring at the connecting area is evaluated by using numerical analyses.
