The Bailey beams are all in a truss structure form, and when the Bailey beams are used as a support or a trestle and other scenes, support fulcrums of the Bailey beams are mostly required to be arranged at strong node positions. In consideration of the complexity of the actual use condition, the condition is sometimes difficult to satisfy, namely, in the actual use process, the fulcrum position often appears at a weak node or a non-node, so that the shearing resistance and the bearing capacity of the Bailey truss are far smaller than the structural design value of the Bailey truss.
At present, the bailey structure is calculated by adopting an analysis method of a truss structure, so that the bailey reinforcing measures can only reinforce weak nodes, and the stress form of the structure is still the truss structure. The reinforcing member is reinforced by adopting a reinforcing vertical rod.
However, in the traditional manner of reinforcing the vertical rods, the truss structure of the bailey beam is damaged, the interface shear bearing capacity of the bailey beam is changed from an oblique rod or a vertical rod into a lower chord, and the bailey chord becomes a beam body with complicated stress from a tension-compression rod, so that the bearing capacity of the bailey structure is far lower than the design value.
