Abstract:

Skewed steel I-girder bridges present unique structural challenges due to their angled geometry, which affects load distribution and increases potential for fatigue and stress concentrations. Traditional connection methods, such as bent plate connections, can introduce flexibility, leading to reduced stability. FDOT is exploring Half-Round Bearing Stiffeners (HRBS) as an alternative connection method to improve girder stability and reduce the risk of fatigue.
