Finite Element Analysis on mechanical behavior of orthotropic steel bridge deck in Balinghe Bridge

摘要

Orthotropic plate participates in bridge structure as a part of steel box girder, while in Balinghe Bridge it is used as bridge deck directly to endure the wheel load. In this paper it's studied systematically the mechanical behavior of orthotropic steel bridge deck in combination with the deck model of Balinghe Bridge, and shows the positions emerging fatigue cracks to provide the basis for future health monitoring and put forward some suggestions.
