The characteristics of the longitudinal beams of the Bailey Bridge

The longitudinal beams of Bailey Bridge are divided into two types: longitudinal beams with buckle and longitudinal beams without buckle. Buttons are welded to the buckle longitudinal beams, which are set on both sides of the bridge deck. The bridge deck tenon is placed between the buttons. Four of the buttons are provided with through holes for the edge material and the bridge deck to connect the edge material and the bridge deck through this hole. A buckle stringer connection. The non-buckle longitudinal beams are arranged in the middle of the bridge deck regardless of the front and back sides. Nowadays, due to the large traffic load, the longitudinal beams and wood plank structures are no longer commonly used. Orthotropic steel bridge decks are used in more cases. However, in third world countries, stringers are still in wide demand.
